ABBY (1974)

This black version of THE EXORCIST was sued by Warner Brothers when it first came out due to the blatant similarities here and became pretty obscure for many years.
 It is a pretty goofy retelling of that movie that stars two of my favorite stars from the blaxploitation-era William 'BLACULA' Marshall as a priest and Carol 'THE MACK' Speed as our possessed Linda Blair stand-in.  Speed is especially great as she becomes possessed and vomits up saliva everywhere, kicks guys in the nuts a lot and generally acts super horny and super evil and usually both at the same time.  Though I think the intention was to make a scary film due to these over-the-top insane outbursts I think the movie can't help but be seen as a comedy by anyone viewing it today.  Highly recommended to anyone who can appreciate high-camp value in their entertainment.

BUMMER! (1973)

  A tale of a shitty rock band brilliantly named The Group and the groupies that follow them.  While I wouldn't say this movie is particularly good it does have a couple of cheesy elements that make it watchable and the ending sorta makes it all worthwhile.  Another positive is one of my favorite 70's blaxploitation chicks, Carol Speed as a hot groupie who likes to wear patches on her jeans to show off her ass.  The other interesting character is the fat, sweaty guitarist named Butts who we see go from being just an annoying creepy fuck(a stand-out scene is where he forces 2 girls to strip and then shoves them into a hot shower so that he can watch and masturbate on the toilet) that almost everyone hates and ignores to becoming a rapey, murdery type of a fellow.  You have to wait until around the last 30 minutes or so for the good stuff though and it does get to be a long trek along the way.  The movie is padded-out quite a bit with bad music, a shitty proto-music video that plays like a slide-show and boring relationship talk but if you can make it through all that you get a cool explosive finale.  I guess I'd recommend this one to 70's exploitation/sleaze fans with patience.
 Producer/B-movie legend David Friedman shows up towards the end as a police lieutenant looking a little slimmer than I've ever seen him before.

Typically slow-moving scene!:
