Director Milan Luthria is mighty impressed with Imran Khan. So much so that the filmmaker has paid him a huge compliment - by likening his commitment towards work with that of his uncle Aamir Khan.

While shooting a fight sequence for 'Once Upon A Time In Mumbai Dobaara' (OUATIMD), Imran suffered a bad neck injury. But instead of asking for a break, he continued to shoot.

Says Milan, `We were shooting a scene where he (Imran) had to fall and tumble three-four times on the pavement and roads. No matter how you do it, it's going to hurt. It was only two-three days after shooting the scene that Sonakshi (Sinha) mentioned that Imran was in a lot of pain. That's when I realised that he was trying his best to hide it.`

Adds Milan, `Imran has impressed me with his dedication and sincerity. Despite multiple changes in schedules, he was co- operative and willing. He is going to surprise everyone with his exemplary performance in the film."
