Trust Aamir Khan to always surprise his fans with a different character each time. If rumors are to be believed then the ‘Dangal’ actor will soon get into the garbs of a music composer for a supportive role. Advait Chandan, who has worked as an assistant director for ‘Dhobi Ghat’ and assistant production manager for ‘Taare Zameen Par’, has roped in Aamir for his director debut. Aamir will not be playing the lead role, but an important character in this film which is reportedly titled ‘Secret Superstar’. Buzz is 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, ‘Secret Superstar’ is expected to go on floors in June this year.
