Abhishek Bachchan, who is currently shooting for Ashutosh Gowariker’s Khelein Hum Jee Jaan Sey in Goa is upbeat about his next release Paa with father Amitabh Bachchan. While he plays a politician in Paa, Khelein Hum Jee Jaan Sey is about the Chittagong Uprising in 1930.The actor, who is busy with the film’s promotions, has come up with an unique idea for the film’s premiere. Abhishek plans to pull off a small stunt and enter the venue carrying his father on his back. Amitabh Bachchan, who plays his son in Balki’s Paa hops on to Abhishek’s back in the film and Abhishek has decided to do the same at the premiere. Abhishek and Vidya Balan play parents to Amitabh who plays a 13-year old Progeria patient. The film, which is premiering in Mumbai on December 3, will be a grand affair and the Bachchan’s have personally invited friends from the ad world and film fraternity. The venue of the premiere will be decorated like a children’s nursery. Abhishek, meanwhile, will also start work on Excel Entertainment’s Crooked in which he was supposed to be paired opposite Aishwarya Rai Bachchan. But Aishwarya has walked out of the film citing date problems so now the hunt for a female lead is on.
