Looks like most of the Deepavali releases this year are banking on having more than one version of the lead actor.

Vijay plays a double role in Azhagiya Tamil Magan, hero and anti-hero, while Suriya plays twin borthers separated as babies in the action film Vel. We also have Shah Rukh Khan in two roles in Om Shanti Om, though not a double role, but there are two Oms in the film.

Looks like directors feel that double doses of anything ensures a sure-shot formula for success!
