"It's a very interesting though small part of a theatre and television actor named Abhimanyu. Farhan has been very supportive. I wouldn't have found my way around this industry without him."
But before that, the Delhi dude plays a boorish but benign Bihari waiter in new-director Rajan Menon's Barah Aana.
"I play a waiter. Vijay Raaz plays the watchman and Naseeruddin Shah a driver from North India. We play three friends and migrants in Mumbai who who stay in the Dharavi slums, " reveals Arjun.
The film which also features the Brick Lane actress Tanishtha Chatterjee, acquires an added significance in the light of the recent anti-migrant agitations in Maharashtra.
Says Arjun, "The film was called Bhaiyya to begin with. But the rights to that title were with a Bhojpuri producer."
And last but not the least, Arjun who's a trained actor from Barry John's institute as well as the Lee Strasburg Theatre & Film Institute In New York, has just completed another socially-relevant film.
"The short-film format doesn't seem to leave me, " grins Arjun.
"After doing the two AIDS films with Farhan and Mira I've just completed another short-film for a 10-film omnibus on Mumbai called Mumbai Cutting. My film, the last of the 10, is directed by Ayush Raina.
The others are directed by people like Sudhir Mishra, Anurag Kashyap, Rituparno Sengupta. It l premiereed recently at the Indian Film Festival Of Los Angeles."
