As a Bad Boys lover, I don't think Shahrukh & Salman will be perfect choice as role of Will Smith & Martin Lawrence. If Rohit really wanna remake of this movie, then new actors should be cast.
And, There had already made remake of this movie in 1997, Bade Miyan Chhote Miyan. And, this is nowhere near to Bad Boys. So, I've also doubt that Rohit can pull this movie as good as Michael Bay. So, he should drop this project and should keep concentrate on what shitty he does.
