Remaining guarded about his second Hindi film project, Malhotra said: "All I can say at the moment is that I do have a film in mind and it's not a sequel or a remake.
"As soon as I have a clearer picture I will first tell my producer Karan Johar about it, then share it with the world."
The production will mark the first time the actors have worked on a feature-length film together. Dutt previously performed a cameo role in Farah Khan's 2007 SRK vehicle Om Shanti Om.
A source from the Khar-based production house has reportedly indicated that the movie will be a rugged action project.
Khan recently returned to Mumbai following a 35-day shoot in London on his current Yash Chopra film.
