Karan was seen in a negative role in the film that starred Ranbir Kapoor and Anushka Sharma.
"@anuragkashyap72 in london! About to start filming soon! Write another role fast for me! The actor in me is exploding," Karan tweeted on Tuesday.
Set in the 1960s, "Bombay Velvet" brought back the retro days. The movie was a large screen adaptation of Gyan Prakash's "Mumbai Fables".
The story is about a man with big dreams and the extent he is willing to go to be successful. But its box office performance was disappointing.
Meanwhile, Karan is busy with his next project "Ae Dil Hai Mushkil", which stars Aishwarya Rai Bachchan, Anushka and Ranbir.
The film will release on June 3 next year.
