Raj Kumar Hirani's '3 Idiots' starring Aamir Khan, Madhavan and Sharman Joshi sees the actors playing IIT students much younger than their real ages. Taking a cue from Aamir Khan -Madhavan played badminton as a sport to keep fit.
Reveals a source, "For their role as students the actors needed to look like students. But while playing badminton one day Madhavan injured his knee and had to wear a knee protection bandage."

"Luckily director Raj Kumar Hirani was accommodating enough and went out of his way to especially write Madhavan's role in such a manner that his character had to wear a knee protection bandage in the film," adds the source.


Madhavan had previously injured his knee while playing with ace badminton player Prakash Padukone.
