From overseas news services:

Filmmaker Siddharth Anand, who is busy with his film Bang Bang, will be flying to Los Angeles to work on the visual effects of the action scenes. ...

"It is a breathtaking action sequence whose VFX is being done at the Fox Studios in Los Angeles. Sid Anand would be traveling there for 5-6 days to oversee the process. The best VFX guys who have worked on the biggest Fox Films are going to work on this," a source said on Tuesday.

So there is visual effects work going on in L.A. The stuff isn't all happening in London, Vancouver, and Toronto.

(We even know of vfx work for television now happening in the east San Fernando Valley. Who would have thought?)
