Boss, let me tell you one thing. The kind of courage SRK has in Industry no one else can muster that. And if you are talking about different roles then why do you forget he was the first one to perform anti-hero role in Darr when Amir khan had refused to do that. Same is the case with 'Swades' SRK's best performance ever, completely non-glamorized and down to earth role with emphatic performance. It takes mighty heart to follow in the footsteps of legend like Amitabh Bachchan and if anyone can then it's SRK.
