Anime News Network’s site has an article on the new Trigun: Badlands Rumble movie. This is an older series so some newer librarians might not be familiar with the title. This was one of the funnier series that I have seen. The site also states that the movie will get a limited release in were some theaters will show the English Dubbed version of the film and others will receive the original Japanese undubbed verision. Follow the link to get the English cast listing and the full article. No dates yet on when it will be released on DVD.
