Oooh come on ... that movie is an old one and all the rides are fake. But it's well done. And the "developers" headquarter is obviously in Florida, as you can read right at the beginning.
Those rides are very very blatently fake. If those were real, the speed at which they move would kill people very very quickly due to excessive forces.
What a brilliant and wonderfully conceived documentary! I'm sure Sam Denny and everyone else at Frontier would find TONS of great inspiration if they watch this.
That last ride was byfar my personal favorite!!! [haha]
