The official trailer of Shah Rukh Khan's upcoming movie Zero has been unveiled on the occasion of his birthday today and the trailer is nothing short of unabashed fireworks. Shah Rukh Khan plays a vertically challenged man in Zero, but his character Bauua Singh seems to take life in his stride with full zest in the movie.

Actresses Anushka Sharma as the paralyzed youngster and Katrina Kaif as the spunky superstar, seem to have brought out never-before-seen versions of themselves as well.

Zero is directed by Aanand L Rai and produced by Red Chillies Entertainment and Colour Yellow Productions. The film is set to hit the screens on December 21, 2018.
