Tamil Cinema on OTT: Must-Watch Releases from July to August 2025

From July to August 2025, Tamil cinema has delivered a variety of exciting OTT releases that have kept audiences hooked. Several standout films have impressed viewers with thought-provoking storylines, ranging from high-octane action to heartwarming family dramas. If you’re planning your next weekend binge, here’s a curated list of must-watch Tamil movies now streaming on OTT platforms.

DNA

DNA is a Tamil crime-action thriller directed by Nelson Venkatesan, starring Atharvaa and Nimisha Sajayan in the lead roles. The story follows Anand (Atharvaa), whose life takes a downward turn after a breakup, leading him into alcoholism and eventually to a rehabilitation center. After his recovery, his father arranges his marriage to Dhivya (Nimisha Sajayan), a woman diagnosed with borderline personality disorder.

Anand is aware of her condition but still goes ahead with the marriage. Soon, Dhivya becomes pregnant, and the couple eagerly awaits their first child. However, after delivery, when the baby is handed over to Dhivya post-medical procedures, she insists that it is not the same child she saw during childbirth. Her claims are dismissed by others due to her mental health history—but Anand chooses to believe her. Determined to uncover the truth, he approaches the police to investigate the alleged child swap.

The rest of the film unravels the mystery: Did the couple find their real baby? Why was the child swapped? With a gripping plot, DNA keeps the audience hooked till the very end and has received strong praise from both critics and viewers.

DNA (Tamil Movie) – Cast and Crew

• Lead Cast: Atharvaa as Anand, Nimisha Sajayan as Dhivya
• Supporting Cast: Ramesh Thilak, Balaji Sakthivel, Bose Venkat
• Director: Nelson Venkatesan
• Cinematography: Parthiban
• Music & Background Score: Ghibran Vaibodha
• Editor: V. J. Sabu Joseph

The powerful performances from Atharvaa and Nimisha Sajayan, supported by an experienced ensemble, bring depth to the film’s intense storyline. The visuals by Parthiban and the gripping background score by Ghibran Vaibodha heighten the suspense, while V. J. Sabu Joseph’s sharp editing ensures a tight narrative flow.

Why DNA Stands Out

The suspense kicks in the moment the baby swap is revealed, setting off a high-stakes investigation that uncovers shocking truths and hidden motives. The narrative is tight and engaging, with minimal lag, keeping viewers glued to the screen.

Both Atharvaa and Nimisha Sajayan give powerful, convincing performances that make the story more compelling. Combined with sharp editing and an immersive background score, DNA is a must-watch for fans of intense Tamil thrillers

IMDb Rating & Audience Score

DNA holds an IMDb rating of 7.2/10, showing strong audience appreciation.
According to India Today, which rated the film 3 out of 5 stars, the Atharvaa–Nimisha starrer is “a smart thriller” that keeps viewers engaged, though it takes “a few unwanted detours” along the way (India Today).

Where to Watch DNA Tamil Movie

The Tamil crime thriller DNA, starring Atharvaa and Nimisha Sajayan, is currently available for streaming on Jiohotstar.

3bhk

3BHK is a Tamil family drama film directed by Sriganesh, starring Siddharth and Sarathkumar in prominent roles. The movie tells the inspiring and emotional story of a middle-class family’s relentless pursuit of their lifelong dream—to own a home.

Set across two decades, from 2006 to 2027, the film beautifully portrays the struggles, sacrifices, and hope that drive the characters forward. This relatable narrative strikes a chord with anyone who has ever aspired to move from a rented house into a place they can proudly call their own.

Both Siddharth and Sarathkumar showcase remarkable transformations in appearance and performance to match the evolving timeline. Their heartfelt acting captures the essence of the characters’ journey, adding depth and authenticity to the story.

With its touching moments, realistic situations, and emotional storytelling, 3BHK is more than just a film—it’s a reflection of real-life dreams, challenges, and triumphs that will stay with the audience long after watching.

3BHK Tamil Movie – Cast & Crew

• Cast: Siddharth, Sarathkumar, Devyani, Meetha Raghunath, Chaitra J Achar
• Cinematography: Dinesh B. Krishnan
• Editing: Ganesh Siva

With heartfelt performances from the entire cast, beautiful cinematography by Dinesh B. Krishnan, and seamless editing by Ganesh Siva, 3BHK delivers an engaging and emotional viewing experience.

Why 3BHK Stands Out

3BHK resonates deeply with viewers by portraying the relatable struggles of a middle-class family. Director Sriganesh brings authentic, lifelike characters to the screen, making the story feel genuine and heartfelt.

The film also features captivating dialogues and strong emotional moments that stay with the audience. With brilliant performances by Siddharth and Sarathkumar, the movie leaves a lasting impression.

IMDb Rating & Audience Score

3BHK holds an IMDb rating of 7.4/10, reflecting its strong audience approval.
The Times of India awarded the film 3 out of 5 stars, describing it as a wholesome family entertainer with a realistic and heartfelt portrayal of a middle-class family’s journey to achieve their dream home (Times of India).

Where to Watch 3BHK Tamil Movie

The Tamil family drama 3BHK, starring Siddharth and Sarathkumar, is currently available for streaming on Amazon Prime Video.

Paranthu Po

Paranthu Po is a 2025 Tamil family comedy and musical film directed by Ram, starring Shiva, Grace Antony, and child actor Mithul Ryan. The movie follows a father, Gokul (Shiva), and his son, Anbu (Mithul Ryan), who go on a fun and meaningful bike road trip.

During their trip, they enjoy many beautiful moments — seeing rain fall on one side of the road, watching the sunrise from a mountain, meeting Gokul’s old school friend Anjali and her family, and visiting the farmhouse of Anbu’s friend. These simple experiences bring them happiness and help them understand the real meaning of life, away from stress and problems.

Unlike movies like Thanga Meenkal and Peranbu that focus on a father–daughter bond, Paranthu Po shows parenting in a lighter way with humour, music, and a good feel movie.

Paranthu Po (2025) – Cast and Crew

Shiva,Grace Antony ,Anjali,Aju Varghese,Vijay Yesudas,Balaji Sakthivel,Mithul Ryan

Cinematography: N. K. Ekambaram

Editing: Mathi V. S.

Music & Background Score: Yuvan Shankar Raja, Santhosh Dhayanidhi

With its talented cast, visually appealing cinematography by N. K. Ekambaram, sharp editing from Mathi V. S., and captivating music by Yuvan Shankar Raja and Santhosh Dhayanidhi, Paranthu Po is set to deliver a wholesome family entertainment experience in 2025.

Why Paranthu Po Stands Out

Paranthu Po is a refreshing parenting-based Tamil movie that speaks directly to today’s generation. It delivers valuable lessons for both parents and children — reminding us not to leave kids alone or locked indoors, to encourage and celebrate every little achievement they make, and to truly live in the moment.

The film beautifully shows how even children can teach life lessons to parents, just like Anbu did for his father by urging him to quit smoking. Shiva’s natural one-liner humour adds charm, while the music in certain scenes perfectly conveys emotions and unspoken thoughts.

After its OTT release, Paranthu Po achieved the second-highest viewership, proving its wide appeal among family audiences. If you have kids, this is a movie you shouldn’t miss watching together.

IMDb Rating and Audience Reviews

Paranthu Po has a strong IMDb rating of 7.9/10 (IMDb, 2025), showing that many viewers enjoyed the film. The Times of India gave it 4 out of 5 stars, saying that director Ram’s gentle comedy “finds magic in life’s smallest detours” (Times of India, 2025).

The Hindu called the movie “a breath of fresh air in Tamil cinema,” praising its simple storytelling and emotional touch (The Hindu, 2025). These positive reviews prove that Paranthu Po is a must-watch Tamil family movie of 2025.

Where to Watch Paranthu Po

You can watch Paranthu Po on the Jiohotstar. The film is available for streaming in Tamil, making it easy for family audiences to enjoy from home.

Maargan

Maargan is a Tamil crime and mystery thriller directed by Leo John Paul, starring Vijay Antony and Ajay Dhishan. The story is about a dangerous serial killer who attacks women by injecting them with a strange serum. The victims’ bodies turn black before they die.

Things get personal when the daughter of Mumbai ADGP (Vijay Antony) is murdered in the same way. Determined to catch the killer, he takes the help of a youngster (Ajay Dhishan) who has supernatural powers. Together, they begin a tense and suspense-filled investigation to uncover the truth.

Maargan (2025) – Cast and Crew

• Vijay Antony as Mumbai ADGP
• Ajay Dhishan
• Samuthirakani
• Mahanati Shankar

Crew:

• Director & Editor: Leo John Paul
• Cinematography: S. Yuva
• Music & Background Score: Vijay Antony

Why Maargan Stands Out

Maargan is exciting to watch because the investigation and the way clues are found keep you interested from start to finish. The story moves at a good pace, and both Vijay Antony and Ajay Dhishan give strong performances that make the characters believable.

The climax has a surprising twist, and the movie ends with a meaningful social message. This makes Maargan more than just a regular crime thriller — it’s a film that entertains and also makes you think.

IMDb Rating and Audience Reviews

Maargan holds an IMDb rating of 6.8/10 (IMDb, 2025). Many viewers have praised it as “a solid thriller after a long time.” One reviewer on Reddit mentioned stepping into the movie with very little knowledge of its promotions and being pleasantly surprised by how engaging it was.

They also highlighted that the director, who is also an experienced editor, delivered a crisply edited and tightly packed thriller that kept them hooked until the end.

Where to watch Maargan

You can watch Maargan on Amazon Prime Video and Sunnxt. The film is available in tamil,telugu, malayalam and kannada, making it easy for thriller lovers to stream and enjoy from home.

Kuberra

Kuberaa is a Tamil-Telugu social thriller directed by Sekhar Kammula, starring Dhanush, Nagarjuna Akkineni, Jim Sarbh, and Rashmika Mandanna. The story follows Deva (Dhanush), a simple beggar unknowingly caught in a massive money-laundering scam run by businessman Neeraj Mitra (Jim Sarbh) with the help of former CBI officer Deepak (Nagarjuna). When Deva discovers he is being used and marked for death, he escapes, setting off a tense chase for survival, truth, and justice.

Kuberaa (2025) – Cast and Crew

Main Cast:

• Dhanush as Deva
• Nagarjuna Akkineni as Deepak
• Rashmika Mandanna as Sameera
• Jim Sarbh as Neeraj Mitra
• Sunaina

Crew:

• Director: Sekhar Kammula
• Cinematography: Niketh Bommireddy
• Editing: Karthika Srinivas
• Music & Background Score: Devi Sri Prasad

Why Kuberaa Stands Out

Kuberaa is special because it has a fresh story, a strong screenplay, and keeps you interested from start to finish. Dhanush shines as an innocent beggar, giving a natural and emotional performance that feels real.

Nagarjuna Akkineni also does a great job, perfectly playing the role he was given. With powerful acting and an engaging plot, Kuberaa is one of the must-watch thrillers of 2025.

IMDb Rating and Audience Reviews

Kuberaa has an IMDb rating of 6.4/10 (IMDb, 2025). According to The Hindu, the film “falls short of being a gamechanger,” but it is still “a brave film from a director who has often stepped away from the norm and raised pertinent questions” (The Hindu, 2025).

Where to watch kuberaa

This movie is currently streaming on Amazon prime video.

Conclusion
