Superstar Aamir Khan is likely to feature in Priyadarshan's much-awaited film based on AIDS.

"The project on AIDS is on, but the script is not yet ready... (I had) too many schedules and things to do so couldn't finish the script. I had discussed it with Aamir earlier and that time he wanted to do the film," the director.

The 55-year-old filmmaker has been talking about this project since 2009. It has been learnt that after Priyadarshan wraps up his current project, 'Kamaal Dhamaal Malamaal', he would start work on the untitled AIDS film, which will be without songs, comedy and free of commercial trappings.

"I will complete the script first and approach him (Aamir) again. If he has time he will do it," the National Award winning director said.

Earlier, filmmakers Revathy and Onir had explored this subject (AIDS) in their films 'Phir Milenge' (2004) and `My Brother Nikhil' (2005), respectively.

While 'Phir Milenge' had a star-studded cast that included Salman Khan, Shilpa Shetty and Abhishek Bachchan, 'My Brother Nikhil' featured Sanjay Suri, Juhi Chawla and Purab Kohli. Both films did not have a successful run at the box office but they received critical acclaim.
