Shah Rukh Khan's "Fan" may not have set the cash registers ringing, but its top-draw VFX work is definitely an achievement. A recently-released show-reel by Red Chillies VFX highlights the work that went into making the film.

Besides showing the superstar's transformation into Gaurav Chandana, the clip also focuses on some of the scenes that were doctored on the editing table. The three crucial action scenes — one in Dubrovnik, the climax and another from when Gaurav is seen trying to escape the cops — were shot with quite a bit of help from the computers.

The before-after frames give a clear picture of the kind of hard work that went into making the technologically advanced film, which probably deserved much more than what it got at the box office. However, it was not just the VFX and the prosthetics: SRK, too, needs to be credited for the roles he played.

"I was the oldest one on the set. All these kids were very patient with me. Wearing the prosthetics wasn't easy. I used to get irritated as the sweat used to stick to the face. But they did bear with me. We have worked very hard so that it does not look unreal. Also, as I am a known face, it is not easy to play a 50-year-old and then do a half-age character," the Press Trust of India quoted SRK as saying.

In other news, SRK will be next seen in "Raees," Gauri Shinde's untitled film alongside Alia Bhatt, and Aanand L Rai and Imtiaz Ali's upcoming projects.
