Trust Aamir Khan to always surprise his Bollywood fans with a different character each time he takes up a role. If rumours are to be believed then the ‘Dangal’ actor will soon get into the garbs of a music composer for a supportive role in one of his upcoming Bollywood films. Advait Chandan, who has worked as an assistant director for ‘Dhobi Ghat’ and assistant production manager for ‘Taare Zameen Par’, has roped in Aamir Khan for his directorial debut. Aamir will not be playing the lead role, rather the celeb of the cinema world will be seen in an important character in this film which is reportedly titled ‘Secret Superstar’. Buzz is that that this is a musical film exploring the relationship of a mother and a child. While the rest of the cast has not been zeroed in apart from Aamir Khan, ‘Secret Superstar’ is expected to go on floors in June this year.
