First off, the title change happened a while ago, so if you are still calling it Transformers: Rise of the Fallen, correct yourself before nerds every where beat you to death. Rainn Wilson will join Megan Fox, Shia LaBeouf, John Duhamel and John Turturro in cashing checks for years to come when Troth (Transformers: Revenge of the Fallen) hits theaters this summer on June 26, 2009.
IGN cornered screenwriter Roberto Orci at a party and got these nuggets and more out of the man ...
The outrageous, crazy humor is more outrageous, but then so is the serious side of it and so is the stakes of the Transformers plot and the seriousness with which some of their mythology is treated.
So it sounds like Orci thinks the original just isn't good compared to the sequel, since the sequel is better in both the comedy and drama department ... way to undersell it man.
He also let it slide that there is a Pretender in the sequel.
