It is now confirmed (by the man himself) that Imran has finally signed on for his next movie which is tentatively titled "7 days in Paris" and which will also feature Katrina Kaif as his co-star.
"7 days in Paris" will also be Sanjay Gadhvi's next movie after Kidnap and is a Romantic Comedy.

Imran's words at IKF :
"My next film is tentatively titled '7 Days in Paris'. It's a romantic comedy (a little more rom than com) directed by Sanjay Gadhvi, and costarring Katrina Kaif (she's very sweet. And very hard working).[...]Obviously, at this point I can't tell you stuff about the film because we're still in pre-production,[...]Also, I don't know if we'll stick with the title because the conventional wisdom is that you shouldn't have complete English titles. Hindi's better, so it might change."
