I'm For The Hippo

This is a earnest request to all those who are reading this post AND all those who know some place where I can buy an "I'm for the Hippopotamus" movie DVD (English). Hope I didn't reduce the sample population with my AND condition!! ;) This movie is a laugh-riot starring Terence Hill and Bud Spencer. T&B have a lot of movies together like Trinity is my name, My Name is Trinity etc but "I'm for the Hippo" is my favourite.

I searched everywhere but found only non-English DVDs of the movie. That's why this! For those who have no clue who these two actors are here is a good website which gives good information. (Beware the web page has a irritating/holographic background!) The image here on this post is linked to some German website. I can't understand why 2 English speaking actors in an English movie are nowhere to be found! And everywhere to be found in non English domains!!
