First, you have to realize that Fred Olen Ray's "Beverly Hills Vamp" is NOT intended to be taken seriously, so if you watch it and end up complaining that it's "mind-numbing drivel" (to quote the previous reviewer), then you totally missed the point. The whole point is to be silly and show scantily clad babes, as Ray also did with "Evil Toons" and "Teenage Exorcist". With the presence of Eddie Deezen (who played the chatterbox Beatlemaniac in Robert Zemeckis's "I Wanna Hold Your Hand" and the obnoxious ventriloquist in Steven Spielberg's "1941"), you know that you're in for something zany.
What I mean by the link to Peter Sellers and the Beatles is a loose connection. Britt Ekland was one of the many blonde sexpots of the '60s. She was married to Sellers for a few years. Peter Sellers co-starred with Ringo Starr in "The Magic Christian", a mockery of the British class system. Christopher Lee appears briefly in the movie as a vampire. Years later, Eddie Deezen appeared in Zemeckis's movie as a man modeling himself on Ringo. That's the connection.
Anyway, this is a movie that you just have to accept as totally silly. That's all that it is: nice, silly fun with a lot of hot babes.
I'd bed Britt Ekland any day.
