Reports are suggesting that Tim Burton might not be the director for the upcoming film, Ripley's Believe it or Not!, according to ComingSoon.net (http://www.comingsoon.net/news/movienews.php?id=21120). The chances that the film would begin shooting after Burton completed Sweeney Todd were in doubt before, until Steve Oedekerk wrote a new draft of the screenplay, which gave some hope to the future of the project. No official news are up yet at the moment.
Also, it looks like Sweeney Todd has completed principal shooting, according to Playbill News (http://www.playbill.com/news/article/108819.html). The macabre musical will now begin post-production and should be ready for its U.S. limited release date of December 21st, 2007.
