If you missed LEGO Atlantis: The Movie (our review of it), you can watch it through the Cartoon Network’s video site – here’s a direct link to part 1 – there are 5 parts. If for some reason that link expires, just check the video site site and browse around for Atlantis.
I do not know how long it will be available online or what, if any, countries it is restricted to.
Still no word on future airings on Cartoon Network, or availability on DVD. It would be cool if they included it on the LEGO Adventures of Clutch Powers DVD, which is LEGO’s first full-length movie. As far as I know, that is not being broadcast anywhere, and will only be available through purchase or rental.
The animation in the Atlantis Movie looks very similar to that of the Clutch Powers movie.
