Apart from grandeur, Shankar's films are also known for its lengthy running time. Pretty all his movies will have a runtime close to 3 hours or even longer than that. 

For the very first time, a Shankar film will have a runtime under 2 hours and 30 minutes. Editor Antony during the audio launch event revealed that the runtime would be around 2 hours and 20 minutes with just 3 songs.

It is said that the runtime is short because the film is made in 3D format. With 3D glasses, it'll be difficult to watch a movie if it's more than 150 mins.
