For the first time in the history of Bollywood, Aamir Khan and Shah Rukh Khan’s films will be releasing within a week of each other.

A trade source says, “Aamir is producing Secret Superstar where he plays a cameo as a quirky musician. He has described his role in it as the tadka in the daal. Child artist Zaira Wasim who plays young Geeta Phogat in Dangal plays the main protagonist. The film will be releasing on August 4 and Imtiaz Ali’s untitled next (tentatively titled The Ring) starring Shah Rukh Khan and Anushka Sharma is releasing a week later on August 11. Now given that both Aamir and SRK are the masters of promotion, expect to be overwhelmed.”
