Newton's 3rd Law (2026) · Telugu · Director: Rajesh Karna · Cast: Sumanth, Jagapathi Babu, Srinivas Avasarala · Crime Noir Thriller

Newton's 3rd Law has one of those plots that sounds genuinely gripping on paper. A double murder in a small 1999 town. An elderly man on edge after a mysterious novel shows up on his doorstep. A measured, unflappable cop — Vasudev (Sumanth) — peeling back layers of family secrets, financial desperation, and karma that binds every player together. The title gives the whole thing a neat, almost scientific backbone: every action gets an equal and opposite reaction. There's real engine here. The problem is the machine never really runs at the speed the design promised.

The good: The setup is taut and the central mystery has genuine pull. The first half is compact and moves — the suspects each have their own secrets, the noir-style rain-soaked atmosphere lands, and the film's minimalist approach is a refreshing change from the over-produced Telugu thriller playbook. Sumanth plays Vasudev with a low-key, unhurried cool that works well in places.

But. The potential of the premise keeps bumping into execution that doesn't rise to it. Jagapathi Babu as villain Stephen Mercury is straight out of the interchangeable Telugu antagonist factory — black suit, cigar, generic menace — and neither the script nor his performance give the character any real specificity. The second half stumbles badly: a potentially sharp twist gets rattled off too fast to land, and the philosophical layer promised by the title is explained rather than felt. You can see the better version of this movie in the cracks — the film needed a surer directorial hand and tighter performances from the ensemble to get there.

The verdict: The plot deserves credit — it's a genuinely nice concept. But a good idea executed at 60% is still only 60%. As a one-watch mystery, it's passable but underwhelming. You'll watch it and think about what it could have been more than what it actually is.

Rating: 2.5/5 — nice plot, weak execution. Worth a watch if it lands in your queue; not worth seeking out.
