The actor will be taking on the role of the villain in the remake of 1990's Agneepath.
He told The Times of India: "I've been working for 32 years now, and I'm comfortable with all genres. But frankly, I have an action image, and that's what my forte is.
"In the middle, the action bit had gone away, and everybody had shifted to comedy and love stories, but it's coming back now."
Dutt added that his traditional villain character in the film is "very strong".
He said: "I was apprehensive in the beginning [about the part], but when Karan [Malhotra] narrated it to me, I was just amazed and I had to do this film. It's not like what Agneepath was, it is totally different - very grounded, very earthy."
Rascals director David Dhawan recently described Dutt as an "open book" and said that he has not changed since their first collaboration, Taaqatwar, in 1980.
