- In January 2008, Warner Bros. announced the film was on indefinite hold, allowing options lapse for the cast. The studio felt the script needed perfecting, which was impossible because of the 2007-2008 Writers Guild of America strike.
- In February 2008 it was announced that production would go to Canada, despite George Miller's wishes to keep production at Fox Studios Australia. The filmmakers are still adamant for a mid-2009 theatrical release date, and hope to have filming start in mid-July 2008.
