Passion Studios is Sivakarthikeyan's self-production banner. Thaai Kizhavi (2026) is the year's content surprise — ₹82 Cr WW Blockbuster verdict with no major stars and a ₹10 Cr budget = 8x ROI, one of the highest in modern Tamil cinema. The Sivakarthikeyan thesis: build IP independent of star valuation cycles. SK reinvests his acting fees from external productions (Doctor for Disney+ Hotstar; Maaveeran for SK Productions) into Passion Studios self-led films. The capital efficiency is striking — Passion typically operates with 3-5 person creative teams and ₹15 Cr or less per-film budgets. The model breaks the Tamil mass-cinema convention that hits require ₹50+ Cr budgets and A-list star vehicles.
