'Chennai Express' is a romance flick directed by Rohit Shetty, starring the kingpin of romance, Shah Rukh Khan and Deepika Padukone.
Shah Rukh Khan was the first actor to be cast in the film, but does not play a South Indian character in the story.
The story is about this man's travel from Mumbai to Rameshwaram and what happens during the journey.
After a lot of speculative reports of the heroine finalized for the film, which also angered Rohit Shetty, Deepika Padukone bagged the role in April 2012.
