R. Madhavan, who plays one of the idiots in Rajkumar Hirani's "3 Idiots", is in pain thanks to a knee injury he suffered during the film's shooting. But despite being advised a few weeks' rest, the actor continued working and says he won't slow down until the movie releases.

The star has been vigorously promoting the much-awaited film that also stars Aamir Khan, Kareena Kapoor and Sharman Joshi.

"I don't care for the moment though," Madhavan said with a smile. "Along with the rest of the cast and crew, it is my responsibility to make sure that '3 Idiots' is seen and heard all over. I don't mind stretching a little extra," he said.
