Amitabh Bachchan has explored many genres, but says working in mystery thriller "Badla" has been the most rewarding experience for him. After working on Sujoy Ghosh's "Badla", Big B will team up with actor Emraan Hashmi for yet another mystery thriller.

"Working on this mystery thriller has been a most rewarding experience for me. Sujoy Ghosh, the director of the film, needs to be given credit for putting this intricate tale in a most exciting and watchable manner," Big B said.
