The movie has been co-produced by Sanjay Dutt Productions and Rupali Aum Entertainment.
"Arjun is happy to do the cameo, " said a source close to the actor.
The actor had become quite choosy about his projects ever since he was lauded for his performance in "Rock On!!" and received a National award for it too.
He followed up the success of "Rock On!!" with films "Raajneeti" and "We Are Family".
