"The director is from New York who has made slightly international cinema - Dev Benegal. So, it's a very interesting concept," the 33-year-old said here during the making of a green tea ad film.
"It's not a thriller, it's a very whacky film, something which my fans would not expect me to do," she added.
Benegal is known for films like "Road, Movie", "Split Wide Open" and "English August".
Kareena added that "Bombay Samurai" will be the first of its kind film which will have both an international and a commercial release.
"I am doing a very interesting film which is going to star Farhan Akhtar and me. I have never worked with Farhan, he directed me in 'Don' when I did the song. It's also going to be an international film which is going to be the first of its kind, which will get an international release apart from releasing in mainstream cinema here," she said.
Kareena is currently shooting for Rohit Shetty's "Singham 2."
