South actor Mammootty desperately wants to work in Hindi movies, but only in the worthwhile. Which director will he prefer? "It doesn't matter whether the film is a Subhash Ghai project or a Deepa Mehta project. For me, the script in the Hindi film or any film has to be worth doing. I am always on the lookout for something exciting. I am willing to work with a newcomer as well, if the film offers me something worthwhile. I should be sure that the production values will be great."
