The Teenage Mutant Ninja Turtles reboot is certainly going through a number of writers. In 2009 John Fusco (The Forbidden Kingdom) was hired to write the script for the live-action reboot, and then last year Iron Man writers Art Marcum and Matt Holloway were brought on-board to re-work the script.
Now Paramount has hired the writing team of Josh Appelbaum and Andre Nemec, who recently worked on Mission: Impossible – Ghost Protocol for the studio.
In 2010 we heard the movie was being fast-tracked so that it could be released in 2012, but that doesn’t seem likely now. Producer Scott Mednick said the live-action film may employ face replacement technology, which would allow the turtles to be much more expressive. This suggests they could be a mix of both actor and CGI.
