While the Shahenshah of Bollywood Amitabh Bachchan is busy promoting his upcoming finite fiction series Yudh (Endemol India and Saraswati Pictures) (to air on Sony Entertainment Television), we have some interesting tidbit coming directly from the sets of the show. It seems that while shooting with Sarika, who plays his ex-wife, the legendary star got a little playful in an attempt to scare her. It so happened that in one of the scenes where she was supposed to bang the door on Bachchan’s face, Sarika was very watchful and worried that it shouldn’t hit him. Big B took notice of this and decided to play a naughty prank on her. The moment Sarika shut the door on his face he screamed loudly scaring not only Sarika but the entire unit pretending to be hurt. Sarika was almost in tears thinking that she has injured the megastar. In no time AB opened the door and starting laughing at her leaving one and all surprised and shocked. Now, that’s who you call a perfect prankster!!!
