Aamir Khan is making waves by promoting upcoming film "3 Idiots" in innovative ways. But co-star R. Madhavan is unperturbed by the actor hogging the limelight. In fact, he admits that the film is being sold on the superstar's name and he has no problems with that.

"Aamir is the biggest star; so it would be foolish to think that the focus will be entirely on you when he is in the film. We are selling '3 Idiots' on his name, " Madhavan, who had teamed up with Aamir in the hit film "Rang De Basanti", told.

Aamir has launched a game where one has to spot the Bollywood star who will travel across the country in different get-ups in two weeks. His travels have so far taken him to Varanasi, Madhya Pradesh's Chanderi district, former cricket captain Sourav Ganguly's home in Kolkata and Jaipur.

"However, the fact is that the film is called '3 Idiots' and I'm one of the three; so my presence is obviously felt, " said Madhavan.

Releasing Dec 25, the film also stars Kareena Kapoor and Sharman Joshi. Directed by Rajkumar Hirani, it is about two idiots - Sharman and Madhavan - who are in search of the third idiot, played by Aamir.

The 39-year-old actor said it was wonderful working with Aamir again.

"It was great getting back with Aamir and Sharman after 'Rang De Basanti'. We stayed together in a hostel during the shoot of the film and had a great time. Aamir is an outstanding friend and a very loving person. He pursues things till perfection. I have learnt a lot from him, " he said.

The actor, who was an engineering student, refrained from speaking about his role in the film, but said it resembles his own life.

Talking about "Munnabhai" director Hirani, Madhavan said: "He is the most chilled out director I have ever worked for; he is amazing and makes an actor so relaxed on the sets."

So, does he feel that "3 Idiots" has the potential to beat the "Munnabhai" series directed by Hirani?

"Of course. '3 Idiots' has the potential to beat all films, " he said.

Madhavan, who has earlier featured in films like "Rang De Basanti", "Guru" and "13B", is also looking forward to Leena Yadav's "Teen Patti", which stars Amitabh Bachchan and Hollywood veteran Ben Kingsley.
