Here's a feature animation that looks like a lot of fun. It's called 'Astérix and the Vikings.' It was produced by A Film in Denmark. They have put together an English-speaking cast but, so far, there is no release scheduled for the U.S.
Astérix is a very popular French comic book character, created in 1959 as the hero of a series of volumes of comic books by René Goscinny (stories) and Albert Uderzo (illustrations). Uderzo has continued the series since the death of Goscinny in 1977. Astérix is a small but fearless warrior who lives in a village of ancient Gaul, surrounded by Roman legions. He gets superhuman strength by drinking special potions brewed by a Druid. The comics contain humor that appeals both to children and adults.
The movie has a great web site (all in French) with lots of pictures. You should try watching the really cool trailer for the movie. If you want to know more about the Astérix comics, check out the official Astérix web site.
