Actor Gulshan Grover, who will be seen in a double role in Shuja Ali's "Baat Ban Gayi", reveals that film's budget posed a big problem for him as he had to shoot for both the characters on the same day.

"The budget of the film is very low. It's a small film, so I had to switch to double roles immediately. When you are doing both the characters together, you have to change within five minutes," Gulshan said in an interview.

"But it's not just related to changing of clothes, you have to change your character and acting as well. It was a big problem that it was a low budget film.

Gulshan plays a professor and a gay choreographer in "Baat Ban Gayi".

"As an actor it was challenging. I play heroine's brother who is a professor and is searching for groom for his sister. The other character is of a gay choreographer," he added.

Slated to release Aug 30, "Baat Ban Gayi" also features Ali Fazal in double role.
