"The Invasion" reportedly had 2/3rd of its script's content changed by Larry and Andy Wachowski.
It's no secret that Warner Bros. Pictures was not quite satisfied with the work of Oliver Hirschbiegel in its sci-fi horror "The Invasion" and ordered re-shoots on the flick that took place sometime between October 2006 and February 2007. What's new now is that the re-shoots surprisingly turn out to have large tendency in change the film far more substantially than everyone has assumed.
Collider.com has provided an interesting tidbit saying Larry and Andy Wachowski, who got assigned to re-write the script, actually re-worked on over 2/3rd of the picture which sure will bring a different look on the project in turn. The site also revealed that both Warner Bros. and producer Joel Silver seemed to be pretty content with the revision the brothers have made, feeling they have a more commercially viable product on their hands.
Re-shoots on "Invasion" reportedly was decided to be carried out after Warner Bros. saw an early rough cut of the picture and was said to be unhappy with the lack of action in Hirschbiegel's take. Since the German filmmaker was unavailable to do the re-shoots, the company and Silver then hired the Wachowskis who afterwards brought in James McTeigue to direct instead while they re-wrote the script.
