An upcoming film based on the life of sex workers has landed in some major soup after the producer backing the film recently staged a walkout

Ankoosh Bhatt's Kamathipura also faced a hurdle when Konkona Sen Sharma and Sakshi Tanwar apparently refused to be a part of the project.

Insiders say there were some budgetary issues that led to producer Irshad Khan opting out. However refusing to pin-point matters, Khan says, `There were some internal issues, which is why I had to let go of the project. But I have a few other projects coming up and I will love to collaborate with Ankoosh.` Sources close to the actresses had earlier blamed their characters' risque image for turning the film down.
