"There is lots and lots happening! I'm caught in a 'chakravyuh' myself," Arjun told.
"Chakravyuh", directed by Prakash Jha, is releasing Wednesday. Based on the Naxalite movement, the film features Arjun in the role of an IPS officer named Adil Khan. He says it is an "important" and a "must watch" movie.
Meanwhile, he is also caught amidst the action for the F1 after-parties, to be hosted at his upmarket club, LAP, located in the capital's Hotel Samrat.
Arjun is set to make his big debut behind the DJ console this time, and is bringing a line-up of internations DJs to perform during the three-day event, starting Friday.
