Varun says his father has been planning to make the film for a long time with the "Newton" star as he is "one of his favourite actors" from the current crop.
"Dad has been talking about a serious film from a very long time, (but) not with me. He wants to make a film with Rajkummar Rao because he is one of his favourite actors right now. Raj and he have spoken (about it) many times. He has been talking about it a lot and I tell him 'Do it now!'" Varun said in a media interaction.
"With me unfortunately, it's not about my peers, he (David) talks about the people he has worked with. He would say, 'Govinda would have done this scene like that. Salman used to do it this way. Sanju could do so many things!'
"And I would say, 'But look at the number of films they have done!' My parents do this (comparison)," he said.
"When I won't eat, they would get after me, saying, 'Salman eats this much rice!' And I would reply, 'What should I do if he eats so much?'" Varun quipped.
His latest "October", directed by Shoojit Sircar, hit the screens yesterday.
