If you are in the US and looking for a copy of Help! I'm a Fish and don't want to order it from overseas and play it on a multiregion DVD player (although this is what I recommend if its possible), you can go out and look for a DVD called A Fish Tale instead. Other than the altered title screen (shown at the top of this page) and crappier menus and complete lack of extras, this is the same film despite the misleading and holy-crap-that-sucks cover.

Just fyi.
