Dhanush is seen in a cowboy avatar wearing a hat, green jacket and carrying a stun gun on his shoulder in the poster. Actress Indhuja Ravichandran of 'Bigil' fame has been roped in to play the female lead opposite Dhanush in this thriller.  

It is reported that Dhanush, who has been seen in a variety of unconventional characters, is set to play a dual role, which has both positive and negative shades.

'Naane Varuven' marks Dhanush's reunion with his sibling-director after a decade, which doubles the anticipation among movie buffs. 

The siblings, so far,  have worked together in multiple movies such as 'Thulluvadho Ilamai', 'Kaadhal Kondein', 'Pudhupettai', and 'Mayakkam Enna'.
