<span class=normal> Red Chillies Entertainments social comedy Billu, believe it or not, used visual effects to aide in the storytelling. Mumbai-based visual effects major Redchillies.vfx executed all the shots, including crowd replacement, extensive chroma jobs and compositing. Bollywood Hungama met up with Redchillies.vfx Creative Director Arjun Mitra, who explained various shots in the film. Heres a look at a few of them.<BR><BR><br><p class=clear>&nbsp;</p><amp-img width=1.33 height=1 layout=responsive src=https://images.bollywoodhungama.com/img/feature/09/mar/billubehind2.jpg></amp-img><BR><br><p>&nbsp;</p><span class=normal><br><p class=clear>&nbsp;</p>Fight sequence<BR><BR><br><p class=clear>&nbsp;</p>This sequence was shot on location with Shah Rukh Khan and required a lot of work in post-production. The weather was unpredictable, resulting in some of the shots being taken when it was raining, and others when it was sunny. Thus 3D rain was generated and composited in the dry shots. Storm clouds were added in all the shots to get a uniform look. Plus the Redchillies.vfx team had to colour correct a lot of shots before they were finalized. The sword held by Shah Rukh was given a green glow, a computer generated (CG) globe was added to a few shots and basic wire-removal was done. <BR><BR><br><p class=clear>&nbsp;</p><amp-img width=1.33 height=1 layout=responsive src=https://images.bollywoodhungama.com/img/feature/09/mar/billubehind3.jpg></amp-img><BR><br><p>&nbsp;</p><span class=normal></span>
