I think it may be worth noting that there's a DVD of an animated feature out--Van Helsing: The London Assignment. I saw it when I was at FYE picking up my copy of Reefer Madness (also got the Robot Monster/Plan 9 double pack for a mere 10 bucks). It's a prequel of sorts to the movie.
It concerns Hyde in London, which means that they put out a feature that basically is going to have the villain get away before he's killed in the movie. Hmph.
I was considering it, but then I saw that it boasts it has the same director and producer as the movie, so I set it down.
The extra features seem to make it out to be just a glorified commercial for the movie. I could be wrong, but just reading the box gave me a bad feeling about it.
