"I am not in a hurry to work with her. It would be a rare man who would like to work every time with his wife. It would be nice for me to work in a different world and then come home to meet her," Saif told reporters in a group interview.
Directed by Raj Nidimoru and Krishna D.K, "Happy Ending" also stars Govinda, Kalki Koechlin, Ileana D'Cruz and Ranvir Shorey.
Saif, who was previously seen in "Bullett Raja" and "Humshakals", says he was very comfortable doing "Happy Ending" as it was a romantic-comedy.
"It's like a comfort zone because we have worked in this world before. However, within this space we couldn't do the same thing again, we had to do something different. Directors Raj and DK have written a great script with a sense of humour.
"My character has ex-girlfriends and complications in life, there is another character who is his alter ego -- the double role," he said.
The film is slated for a Nov 21 release
