Abhishek Bachchan, who has wrapped up the shooting of Rohit Shetty's "Bol Bachchan", says comedy is the most difficult genre to perform.

"Have always said that comedy is the.....Most difficult genre to perform. 'Bol Bachchan' surely proved that!!" Abhishek wrote on microblogging site Twitter.

The cast of the film includes Ajay Devgn, Asin Thottumkal and Prachi Desai, and Abhishek says shooting with an ensemble cast as been a learning experience.

"It's always a great learning experience when you get the opportunity... To work with a great group of actors. One can learn so much from just observing them. That's what makes an ensemble cast film a lot more...Interesting for me," he wrote.
