"There is a very stylised sword fighting designed by Prabhudheva, and after a very long time, I had to even practice to do action. So it has come out very nicely," the 45-year-old said here Monday at a press conference.

Ajay even had to work on his physique while shooting for the film.

"The character goes through a change-over in the film. So, first he (Prabhudheva) asked me to put on weight and then I lost 17 kg. It took me two months," he said.

Explaining the demand for a change in Ajay's physique, Prabhudheva, who has directed the movie, said: "I asked him to change because there is a bare-bodied sequence."

"Action Jackson" also stars Sonakshi Sinha and Yami Gautam and hits theatres Dec 5.
