Mr Perfectionist Aamir Khan is likely to be roped in for yet another message oriented movie after 'Taare Zameen Par'. The news is that director Priyadarshan is planning to come up with his ambitious movie which would revolve around AIDS and it has been titled 'AIDS". However, he is said to be keen on roping in Aamir for a key role but is yet to approach the star with the details. The film will also have other big names but it will not have any lead heroine, just actresses.
