Tamil star actor and politican Vijay's son, Jason Sanjay is making his directorial debut under Kollywood film banner Lyca Productions, and on Monday, the title of Jason Sanjay's debut film was revealed to be Sigma. Sigma stars actor Sundeep Kishan in the lead, and the first look poster features Sundeep sitting atop a pile of gold bars, and stacks of money. 

Sigma's first look comes a year since the film's announcement, and is very gen-Z coded with its title—a pop-culture reference to 'lone wolf' males, and AI imagery in the poster. Prior to the first look release, the team had revealed another poster where Sundeep Kishan was seen facing a big vault door, at the end of what looked like a library. 

Sigma has Thaman S for music, and Krishan Vasant for cinematography.
