Director and producer Aanand L. Rai, who is busy in post-production of his forthcoming film Zero, says Salman Khan and Shah Rukh Khan never made him realize they are superstars while working as they came together for a special song in the film. He was interacting with media at the trailer launch of Happy Phirr Bhag Jayegi along with actors Diana Penty, Sonakshi Sinha, Ali Fazal, Jassi Gill, Aparshakti Khurana, Piyush Mishra, co-producer Krishika Lulla and director Mudassar Aziz in Mumbai on Wednesday.

With Salman and Shah Rukh coming together in a song in Zero, a teaser of which released during Eid, Rai, asked how it felt working with two superstars, said: "I was very happy there." Asked whether it adds pressure on a director while directing both of them in one frame, he said: "I don't think so.. I have been very fortunate in that way. I am not telling this as a director, I am telling you this as a human being.
