Up to this point a rumored total of 40 has been touted, however a new Variety articles ups that to a good 60 after speaking with TF2 VFX lead Scott Farrar. The characters will also see much more interaction and have human like properties such as sweating.
“Michael took the production value up many, many notches,” [ILM’s lead VFX supervisor for TF2 Scott Farrar] says. “Just the backgrounds alone are huge. It’s a combination of ‘Apocalypse Now’ and ‘Ben-Hur,’ in regards to fantastic backgrounds and the unbelievable sets we worked at around the world.”
Everyone involved in “Revenge of the Fallen” is keeping the details under wraps, but Farrar says there are some 60 robot characters, and they play in settings around the world. Some, like refineries at night, were chosen to boost the visual drama and show off the scale of the giant ‘bots.
What’s more, this time the Transformers will interact much more with the world around them. Farrar highlights “the splashes and the hits and the fighting on dirt or moving, banging into trees,” explaining, “Things splinter and break, they spit, they outgas, they sweat, they snort.”
One new challenge is that several sequences will be shown in Imax format, approximately 16 times larger than 35mm, which means the CG work must be finished at much higher resolution. At that scale, it can take several days to render a final frame.
All this is on top of creating a new family of giant robots. “(Bay) had to learn a whole litany of new things by getting into this robot culture on the first film,” Farrar says. “I don’t think he’d ever worked on a film where he’d done so much directing of animated characters. So he’s really taken it to heart, and I think not everybody does, but he actually enjoys the process.”
