Double Role

Was going thru the list of releases this deepavali in both Tamil and Hindi movies. And to my surprise for some strange reason a lot of the movies released has the protagonist playing double role in the same movie, either because of rebirth or twin or just 2 individuals who look the same. These movies are Om Shanthi Om, Azagiye Tamil Magan and Vel. It looks like we are going back to the 70's and 80's when we had a lot releases based on this concept.

P.S. My blog is based on what i have read and not watching the movie. So incase it does not have hero playing a double role kindly excuse maddi.
