Ape Man (1943) with Bela Lugosi.
It's only 63mins, but feels longer. Not a great transfer, but Lugosi does manage to make the ape man sympathetic.
To be honest I kinda lost interest in this one, but the plot seemed to be scientist (Lugosi) accidentally turns himself into half man half ape, hirsute!!! and then decides an injection of spinal fluid will fix things, at which point a rampage occurs.
It has 4.3 on IMDB. Even as a b-grade fan, it was slow. More a 1-2 for me.
Point of Terror (1971)
Tony, our hero, is a nightclub singer who dreams of stardom. Tony doesn't have much time (not sure we find out why, although ironically the actor died in 1973 - when the movie was finally released, so y'know, foreshadowing). Tony commits adultery to hopefully get a recording contract. The movie was on a horror compilation, so far it's far more poor acting, slightly sleazy, and script writing of the worse kind. But yes, better than ape man. Awesome cheesy 70s soundtrack, in fact I've found you the opening credits... the full movie is also on youtube. More exposition than you can shake a stick at, brilliant! The woman who is going to make Tony's career, is married to a wheelchair bound ex-music executive, she apparently had her own life before marriage. Tony meanwhile is having nightmares of stabbing. We don't know why. Tony's adulterous manager has now knocked off her wheelchair bound husband, in a twist, he screamed in pain when she knocked his legs. He then drowned in a swimming pool, something the Para Olympics may contest as unlikely. This has made Tony an accessory to murder, apparently. Oh yeah, more 70s cheese music, and they're (tony's other woman) riding through forests on horses, following by snogging on the beach in the sunset. Oh right, this other woman is the managers daughter, tony has broken it off with the manager who took it poorly, and has gone for a flight down the hill - courtesy of Tony. She's looking a bit broken now.
Eh definitely not a horror, but OK background crap.
