up only once on screen – for 'Andaz Apna Apna' in 1994 - but have always expressed their desire to work again.
The 'Lagaan' star also praised Sanjay Dutt and Ranbir Kapoor, who is the Hindi film industry's latest heartthrob.
"Sanjay Dutt was fantastic, entertaining in 'Munnabhai' series. I liked Ranbir Kapoor in 'Barfi'. I and Kiran (Aamir's wife) were watching the film together and I asked her "what is it that he is doing and I am not. What I need to learn from him".
Aamir, who is known for his meticulous planning, execution of roles and film production, said he feels happy when movies of his contemporaries do well at the box office.
He appreciates good work of others. "Good work gives me joy. And it does not matter that it is not mine. I don't have that kind of competitive spirit in me."
The 'Taare Zameen Par' director said stars have a limited influence on the box office outcome, but beyond a point it is the film and its content that matters.
"Stars have the potential to influence the first three days of the number of people coming in theatres... beyond that we don't have any influence.
"A lot of people attribute the success of '3 Idiots' to me... (But) it is not my film it is (director) Raju Hirani's film. No film runs on the strength of the star alone.
"I think if a film is not good enough I won't be able to make a mark for myself. When a film is good, it does good business," Aamir added.
