Tamil & Telugu Reference Table

1. 8 Thottakkal (Tamil) — JioHotstar

Rookie cop Sathya loses his loaded service pistol, which ends up in the hands of a desperate, depressed man named Moorthy. What follows is a chain of crimes — including a gripping bank robbery — as Sathya races to recover it. Inspired by Akira Kurosawa’s Stray Dog, this Sri Ganesh directorial is a rare Tamil thriller built on guilt, responsibility, and human desperation rather than just action. Starring Vetri and Aparna Balamurali, it’s a slow-burn that rewards patience.

2. Evaru (Telugu) — Amazon Prime Video

A woman kills her lover, DSP Ashok, claiming self-defense. A corrupt cop, Vikram Vasudev (Adivi Sesh), is assigned to unravel the truth — and what he uncovers is far more layered than it appears. A remake of the acclaimed Spanish film Contratiempo, Evaru is a masterclass in plot structure. Every scene plants a seed for what’s to come. If you love films that make you second-guess everything, this is it.

3. Naan (Tamil) — SunNXT

After burning his family home following a devastating personal betrayal, a young man is released from juvenile prison and boards a bus to Chennai. When the bus crashes, he assumes the identity of a deceased medical student and enrols in college — beginning a fragile new life that could shatter at any moment. Vijay Antony leads this slow, emotionally charged identity-thriller that’s unlike anything in mainstream Tamil cinema.

4. Kshana Kshanam (Telugu) — Amazon Prime Video

One of Ram Gopal Varma’s finest, this 1994 classic pairs Venkatesh as a small-time thief with Sridevi as an innocent woman unwittingly carrying a clue to a stolen fortune. Chased by gangsters, cops, and the thief himself, the film unfolds as a hilarious yet genuinely tense road thriller. Paresh Rawal adds terrific menace as the villain. Timeless fun — and criminally underrated by younger OTT audiences. Also check out our coverage of latest South Indian OTT releases on TechnoSports for more picks.

5. Thegidi (Tamil) — JioHotstar

Ashok Selvan plays Vetri, a sharp criminology graduate who joins a private detective agency and gets assigned to tail suspects in a forgery case. But when his targets start dying one by one, he becomes the prime suspect. As the conspiracy spirals closer to home — threatening both his mentor and his love interest — Vetri must think faster than anyone around him. A taut, intelligent thriller that launched Ashok Selvan as a name to watch.

6. Zombie Reddy (Telugu) — Amazon Prime Video

Set during the COVID-19 lockdown, game developer Mario travels to Kurnool for a wedding — only for a vaccine-triggered virus to turn locals into flesh-hungry zombies. What makes this Prasanth Varma film special is how it blends Rayalaseema’s famous faction culture with pure zombie-horror comedy. Teja Sajja is effortlessly watchable, and the film never takes itself too seriously. A wild, unique ride that proves Telugu cinema can do genre mashups brilliantly.

7. Kuttram 23 (Tamil) — ZEE5

ACP Vetrimaaran (Arun Vijay) investigates a series of mysterious deaths linked to an illegal sperm bank racket. The case gets personal when his own sister-in-law becomes entangled in the scandal. Kuttram 23 is a medical crime thriller that goes to genuinely disturbing places — and pulls it off with conviction. The procedural pace keeps you engaged throughout, and the subject matter makes it one of the boldest Tamil thrillers of its era.
