(Hammerhead doubled it's VFX shots for The Fast and the Furious sequel with 150 VFX shots, compared to the 70 VFX shots of the first installment. They worked on the Bridge Race sequence. Like The Fast and the Furious, they shot backgrounds of the streets, then foreground elements of the actors in their cars were shot against greenscreen. The backgrounds were tracked and composited with the actors. And to mime live action streaking, they use a sub-frame camera shake)
