I know the title is misleading, but now we have the situation that a Disney owned company, in this case ILM, works on an attraction for its biggest competitor. Race Through New York Starring Jimmy Fallon If I'm not mistaken ILM worked already on some other themepark projects for various clients.
Interesting that they appear to have done some motion capture stuff, but also filmed the same scene like a traditional production; I wonder what they're planning to do with that I really can't say I'm looking forward to this attraction. Fallon is my second-favorite late-night Jimmy (I think Kimmel is better by a wide margin; he actually makes the program about his guests, rather than himself...crazy concept!), and it seems like the type of thing that will become dated quickly, though I guess Universal is pretty good about changing things out on a regular basis
ILM has been making effects for various companies since they began. That is nothing new. Companies work with other companies all the time even if their parent company is a competitor. In fact, Dreamworks is responsible for the CG movie It's Tough To Be A Bug. Pixar didn't have time to work on it since they were deep in production for A Bugs Life.
