MGM Animation returning

  MGM Animation was last seen in 1996 with All Dogs Go to Heaven. I wasn't really a big fan of MGM since I never seen any of there movies. But I guess there were popular. Now MGM will make there next feature film, Punk Farm.
   Variety says that The Simpsons Movie director David Silverman will rewrite Jim Hecht‘s script and then direct the project. The story, based on Jarrett Krosoczka‘s book, is about “five barnyard animals (Sheep, Pig, Chicken, Goat and Cow) who form an underground rock band.” The book got no small amount of acclaim, and a sequel (Punk Farm on Tour, in 2007). DreamWorks was once developing a film, but the rights passed to MGM at some point.
  I don't know about this film it doesn't sound good to me.
