The 48-year-old actor, whose "The Lunchbox" relied on subtlety and silence in a romantic relationship, said films should have scope for unspoken exchange of love between characters.
"This is what I miss sometimes in our stories, there is not anything which is unsaid, everything has to be said. It becomes very boring as an actor. You are looking for a director, who is ready to explore and bring a new layer to it.
"There is something you can see and hear but there is another story which you are seeing but nobody is saying it. Like what happened in 'The Lunchbox', unsaid was much more powerful than what was said," Irrfan told PTI.
The "Qissa" star feels real-life romance is much deeper than just looking dreamily at your lover and films should explore the gamut of emotions a person goes when he/she is in love.

"We haven't seen romance dealt in the way 'Piku' does. In our cinema romance has some definition and in that area it circulates. It does not go deeper, does not go in the periphery and does not see where it is coming from.
"Piku", also starring Amitabh Bachchan and directed by Shoojit Sircar, released today.
