Zero is turning out to be the most challenging film for Shah Rukh Khan in many ways. The film sees Khan essay a dwarf. Naturally, VFX is at the center of things, with advanced visual effects being used to make Khan's character three feet tall. One of the most-awaited forthcoming films, interest had sparked further when Shah Rukh Khan and Aanand L Rai jointly made the title announcement of their upcoming film featuring the star as a vertically challenged character.

Zero, as the title reads, gave a glimpse of SRK dancing around in a vest and boxers. Since then the posters - one featuring Shah Rukh and the other, a title poster that sees a sky full of stars over the horizon with the title Zero on it and a caption that reads, "Hum jiske peeche lag jaate hain...Life bana dete hain" – have been stoking interest, along with the teasers.
