The 'Golmaal 3' actor, who shared screen space with Saif in the 2013 zombie-comedy "Go Goa Gone", says it is a perception that when two actors meet they only discuss movies.
"Saif and I collaborated on 'Go Goa Gone' and discussed the project extensively. Other than that, people perceive us in a different way... Like when we meet we discuss films. In our case we have been in films every single day of our lives.
"We don't really talk about films so much but obviously when movies are up for release you discuss what is the movie about, how happy are you with the movie. We never discuss what should I do in my career or should I do this kind of a role," Kunal told PTI.
32-year-old Kunal married Saif's sister Soha Ali Khan earlier this year.
The actor says even though the couple was "scared" of tying the knot, they are calmer now.
"I was very scared of getting married, both of us were, because everybody says things change after marriage so we got married at home to make sure nothing changes. "We are more calm now. Because everybody was asking us about marriage, our families, friends, the press... So that's gone. We both are relaxed. Life is pretty much the same. We have been in a very comfortable space because we have also lived together before we got married."
Soha, 37, made a brief appearance in "Go Goa Gone".
When asked if they have plans to star together in a film, Kunal said, "Firstly, we will never do a movie together just because it is offered to us. If she likes it as an actor and I like it as an actor only then we will collaborate.
"So there is no effort from our side to say 'Oh let's a find a film to do together," he added.
Kunal will be next seen in adult comedy "Guddu Ki Gun", which marks his second film release post marriage.
The actor says he does discuss film projects with his wife but so far marriage has not influenced any of his movie choices.
"We connected as friends first and we value each others opinion a lot as actors also. When a film comes our way we discuss it with each other, pros and cons, what we think.
Obviously, the decision finally remains with us. We respect each other's decisions.
"So far it (marriage) hasn't affected my choices. I don't think it should. It should be your own decision like 'Enough of this and these kind of films, now I want to do that.' I still wouldn't do the films I didn't if I weren't married and I still would do the films I do, now that I am married," the "Kalyug" star said.
