It seems Sanjay Dutt's favourite genre is comedy -- he returns in a comic avatar in his long delayed film "Chatur Singh Two Star" to tickle the funny bones of the audiences after entertaining them with "Double Dhamaal".

Directed by Ajay Chandok and co-produced by Pen India Pvt. Ltd and Lotus Pictures, the film, which also stars Ameesha Patel and Suresh Menon, Anupam Kher, Shakti Kapoor, Satish Kaushik in prominent roles, is releasing Friday.

The shooting of the film was completed in 2008 and it was planned to be released in 2009, but was delayed due to market conditions. And Sanjay is hoping that the film works well at the box-office.

Made at a budget of Rs. 25 crore (approximately), it will be released on 700-800 screens across India. A blend of comedy and action, "Chatur Singh Two Star" was shot in Cape Town, South Africa, and Mumbai. The music of the film is being composed by Sajid-Wajid.

The satellite rights for the film have been sold for Rs.8 crore.

The film is about a clumsy cop Chatur Singh who botches up cases and his goof-ups embarrass the police department. Despite his clumsiness, Chatur Singh embarks on an important investigation and jets off on a secret mission to South Africa along with his right-hand man Pappu Panther (Suresh Menon). This is a lifetime opportunity for him to prove himself.

Both of them bump into Sonia (Ameesha Patel) and with her help, Chatur Singh succeeds in finding the right clues and while doing so he kicks off a string of hilarious events.

The small budget movie is based on novel "Chalaak Jasoos" written by a Nagpur-based writer, M Raza. And Sanjay even changed his look for his role. The novel describes the main character as a clumsy guy with a funny moustache and the actor will be seen sporting something similar in the film.

Sanjay also put on weight to fit into the character.

The actor not only worked on his look but has also sung a song for the film. After singing for "Munnabhai" series, Sanjay has crooned two songs in the film -- "Murga anda dega" and the title song "Singh Singh Singh...Chatur Singh Coming".

Rumours were abuzz that the film is inspired by "The Pink Panther", however, Sanjay denied any similarity between the two films.
