The pair will star in the film, which is based on Manto's take on the madness of partition in 1947. The story depicts the irony of the situation through the lunatics in a mental asylum in 1947.

Aamir is said to have been impressed with the script and will play the character of a mentally retarded person in the asylum.

If the actor agrees to work in the film, it would be his second movie on the subject. He had earlier starred in Deepa Mehta's 'Earth-1947', which was an adaptation of Bapsi Sidhawa's novel 'Ice Candyman'.

The film will be directed by India-born filmmaker Pan Nalin, who has earlier directed highly acclaimed film 'Samsara'.

Nalin hopes to rope in Winslet for the project but if she rejects it, he will approach Rachel Weisz to play the role of Dr Sophie in the film, the website said.
