I've just this minute ordered it from Amazon. 'Twas £6.54 and it has the name My Son the Vampire. It's being sent all the way from the crazy old US of A for £1.24.
Unless I'm mistaken, the version with the MY SON THE VAMPIRE title is the slightly edited US release version (which omits the names of the two stars from the credits!).
I want the good old fashioned God-Save-The-Queen BRITISH original release version.
"If you don't know the answer - change the question."
I purchased the unaltered version from the U.K. and use a region-free player, here in America, to see the film. This film is also scheduled to be shown, later today, on the TCM channel and my hope is that, given TCM's sterling reputation when it comes to the presentation of films, the film will finally be shown in America as it was originally made.
Yeah, well fellow movie fans you are sadly in the know now. It was the brutally appended original with what I thought was a parody of Allen Sherman who had a cleverly funny Lp about that time called My Son The Folksinger full of song parodys in what used to be called "Jewish humor." According to people who should know, it was Allen Sherman himself doing something not even up to a clown song at a children's birthday party.
I'm in the UK and I bought the US version, the Alan Sherman version. You're in the US and you managed to buy the UK version, which I have never found! The internet has really changed things.
