Sigma opens strong in Tamil Nadu, but the October 2 box office remains flat. The Jason Sanjay-directed action thriller took the top spot on Day 1 with a modest all-India gross, outpacing Thella Kaagitham and Don’t Trouble The Trouble — both of which struggled to gain traction despite their marketing pushes. But 'strong' here is relative: none of the three films made a dent in the wider market. The numbers are low enough that even Sigma’s lead feels fragile. Its opening was driven almost entirely by Tamil Nadu, where it reportedly drew better response than in Telugu-speaking regions. That regional split could be telling. Sundeep Kishan’s film had a bigger Telugu States debut than its Tamil counterpart, but still underperformed. Thella Kaagitham, a low-key release with minimal pre-launch noise, did slightly better in Telugu states than expected. Don’t Trouble The Trouble, backed by a star-studded campaign, flopped hard. It earned the highest Telugu States gross among the trio. But not high enough to matter. The entire slate opened quietly, with no standout performances. Word-of-mouth will decide who survives the weekend. And right now, there’s nothing to suggest any of them will. The real test begins Friday.
