Comedy is the tough genre: Abhishek Bachchan

Bachchan, 35, who is expecting his first child with wife Aishwarya, says he has completely forgotten the genre in three years. The actor is currently shooting his next comedy ``Bol Bachchan`` with Ajay Devgn and Asin.

"I have almost forgot how tough comedy was. Ajay Devgn just reminded me that the last comedy I did was ``Dostana`` that too 3 years ago. It``s a very tough genre!," he posted on Twitter.

Bachchan was paired with John Abraham in the film that explores the story of two men who pretend to be gay, so that they can rent an apartment from an old lady.

" It is toughest infact... completely drains you. but working with great co actors is such a high! they make you better," he added.

The duo will return in another untitled film which will be written and directed by Apoorva Lakhia.
