The makers of Shah Rukh Khan's starrer Zero have unveiled a behind-the-scenes video detailing the extensive VFX which went behind making Bauua Singh's character.

With 1600 VFX artistes worldwide, the video clip shows the various methods by which the optical illusion was achieved.

While talking about the making of the film, Shah Rukh said, `We realised that this film couldn't be shot in a normal way".

Sharing the video, Shah Rukh Khan tweeted saying, "Ek chota aadmi banane ke liye bade logon ki badi mehnat lagti hai. Proud of the entire @vfx_redchillies for the fantastic work!".

The actor further explained that how the team of VFX specialists had to visualize every scene with the aspect that one character was one and a half feet shorter than the rest

Lego-like sets were created for the film. Instead of the floor, movable boxes were placed so that Shah Rukh's character could be placed at a lower height. As his body had to be shrunk too, they had to take separate shots for that as well.

'Zero' presents the story of Bauua, a vertically challenged man essayed by Shah Rukh Khan. Set against the backdrop of Meerut, 'Zero' presents a unique as well as rooted story.

Bringing back the super hit trio of Shah Rukh Khan, Katrina Kaif and Anushka Sharma, 'Zero' offers interesting performances with an unconventional storyline.

Red Chillies Entertainment and Colour Yellow Productions come together to bring ZERO, produced by Gauri Khan, starring Anushka Sharma, Katrina Kaif and Shah Rukh Khan. The Aanand L Rai directorial has released on 21st December 2018.
