JP Dutta's "Paltan" was supposed to be a comeback for Abhishek Bachchan but the actor pulled out of the film at the last minute and the director says he is clueless about the reason behind the actor's departure from the project.

It was with Dutta that Abhishek made his debut opposite Kareena Kapoor in the veteran director's "Refugee" in 2000. He later collaborated with the director again on the films "LOC Kargil" and "Umroa Jaan". Abhishek was initially attached with the war-drama but he reportedly backed out of the film two days before the shooting commenced.
