Superstars Amitabh Bachchan and Aamir Khan underwent rigorous action training and learnt sword fighting for the upcoming film Thugs Of Hindostan. The senior actor says it's best to put aside apprehensions when one commits to a project. The high-on-action film is directed by Vijay Krishna Acharya.

"Much before we actually went through these sequences, Viktor (Acharya) and Adi (producer Aditya Chopra) had said, 'Maybe you should train a bit'. So, we were doing a lot of sword moments in the gym. There is a lot of action, whether it is jumping off a building, doing summersaults, diving, climbing up. These were all done live," Amitabh, who plays the role of Khudabaksh in the movie, said in a statement.
