If you have a good team of actors and technicians and a good masal in ur head you can remake any Hollywood Movie to Indian Standards,yep sorry this one too is a copy

 This one comes from MEMENTO a path breaking movie from the Director of "The dark Knight"  Christopher Nolan ..Memento is dark but still it ask u question of how well would be you placed if you cant remember a thing nor you are sure who you are....

   Though Aamir is a fanctastic actor he should also take into account the fact that we are bubbling with talents ppl with ideas way beyond time and way into heart best example would be His own Taare Zameen par and Lagaan though lagaan was a peel of from an episode of famous serial Nukkad in which the director Ashutosh also was an actor...

  Hopefully he too will stop getting inspired by movies already made.

Just one more Info Aamirs Two other Movies were inspired

Dil hai ki maanta nahin-It happened One night
and Baazi --Die Hard
