The 75-year-old actor told IANS that he had been waiting for the right script to come along since his last major film project in 2007.
The veteran star said: "After Apne I wanted to do more films, but we were not getting a very good script. Otherwise who wants to sit at home? Someone who loves acting, why would he want to stay at home? I'm always in search of good roles."
The Sholay star also spoke about the differences between his off-screen relationships with his sons to how their characters interact in the film.
"In this film Bobby and I share a very different rapport as compared to in real life. We are more of friends there. The relationship and chemistry is very open. It was quite a nice experience and fun to do that," Dharmendra revealed.
The comic production, which has been partially shot in Canada, releases January 14.
