Lots of relatively minor news items on the film front over the weekend, so we’ll give it to you all in one shot, covering Scooby Doo, Green Lantern, Conan, and Alvin and the Chipmunks.

The new CGI-live action Scooby Doo feature, Scooby-Doo! Curse of the Lake Monster starts production this week, with a premiere on Cartoon Network planned for fall 2010 followed by a DVD release in early 2011.

Two more cast members have been announced for the Green Lantern film.  Taiki Waititi and Temuera Morrison (Jango Fett in the Star Wars films), both from New Zealand, have been cast as a friend of Hal Jordan’s, and Abin Sur, respectively, according to Hollywood Reporter.  They join Tim Robbins, Blake Lively, Ryan Reynolds, and others (see “Tim Robbins in Green Lantern”).

Said Taghmaoui (GI Joe:  The Rise of the Cobra) will play the leader of a group of thieves saved by Conan in the upcoming film, according to Hollywood Reporter.  He joins Stephen Lang, Jason Momoa, and others (see “From Avatar Heavy to Conan Villain”).

The third Alvin and the Chipmunks movie will be on 3D, and will be released December 16th, 2011, according to Variety.  The second, released last December, grossed over $200 million in the U.S. alone, less than half its over-all total.
