Filmmaker Rajkumar Santoshi is set to begin production of the grand musical "London Dreams" this year and the real surprise of the project is Salman Khan.

Santoshi said: "'London Dreams' will come in the middle of the year. So I wouldn't like to say much about it right now. But yes, Ajay Devgan and Salman Khan have been signed for it. And A.R. Rahman will do the music."

Ajay is of course is widely considered Santoshi's resident hero.

But some years ago, Santoshi and Salman had teamed up for the comedy "Andaz Apna Apna".

Salman, currently on a signing spree, has agreed to work in new films to be made by Nikhil Advani and Samir Karnik, among others.

"London Dreams" is unlike any film Santoshi has made before.

Moving away from the gut-wrenching trademark action of his films like "Ghayal" and "Lajja", the new movie is based in London and will delineate the life and times of those associated with the Asian underground music scene.

It will chart the rise and fall of an Indi-Rock band, with A.R. Rahman providing the global sounds for this unorthodox Bollywood musical.

The film could be Santoshi's most expensive film to date, as it will try to replicate the flamboyance of Baz Luhrmann's "Moulin Rouge".
