Johar, 42, will play a negative role in the film, which stars Ranbir Kapoor and Anushka Sharma besides the 'Kuch Kuch Hota Hai' helmer.
"I thoroughly enjoyed working with Karan Johar and he will surprise you all when you will see him in the film. A director actually is a very good actor and only a director can understand that," Anurag said.
'Bombay Velvet', a romantic thriller, is slated to hit theaters on May 2015.
Anurag is also set for another acting venture in Sudhir Mishra's 'Aur Devdas' post his special appearances in 'Happy New Year' and 'Bhoothnath Returns'.
"I am working in 'Aur Devdas' for a small appearance. It's a Sudhir Mishra film and I am playing a father in it. I make appearances in films for some emotional reasons. I did 'Happy New Year' for Shah Rukh and Farah," he said.
