Humshakals

Imagine ... and I mean try to 'visualize' what you are going to read next... "After having watched this movie in a cinema-hall, while on your way back (from it), a mad dog crosses your path. wait ... make it more ... let us say, three mad dogs. You are terrified, assuming that the dogs might bite you but. Somehow those dogs know that you have seen 'Humshakals' and that too in a 'hall'. So, instead of biting you they'll all bow down in front of you showing utter respect to the courage you exhibited!" ... I think you got the point. Why did these actors work in this movie. Why?? Certain scenes are quite funny but overall this movie is s**t.
