The Invasion is a 2007 science fiction film based on a screenplay by Dave Kajganich, originally meant to be based on the 1956 film Invasion of the Body Snatchers. According to Wikipedia they shot the film back in Sept 2005. The Studio disliked the first cut so much that they Fired the Director and the Writers!. Had the Film rewritten by the guys who did the Matrix, Re-shot Scenes and had the whole thing reedited in early 2007!
Most film Productions take 10-12 months from the First day of shotting to release. This Film took almost 2 years. If I knowing anything massive re shoots means the film sucked hardcore.
Reports say this First version was low-key. Using little to no special effects but from the Trailer I saw in Tranformers this new version is pretty much Falling UFO's, Zombies, People falling off of Buildings and Crazy Car Crashes
Worst thing is Nicole Kidman had to stay that horrid Blond for over a year. BITCH GO BACK TO RED.
