All-American Murder (1991) College weirdo has just one day to prove he's not a murderous psycho. If nothing else, worth it for Christopher Walken's dialog. TIL: In the Genesis creation story, the word day (yō·wm) can mean 24 hours or a long indefinite time. Take your pick.
Mamba (1988) Woman's embittered Ex imprisons her in a house with a souped-up venomous snake. Trudie Styler gives it her all, but it's all just a bit too average. TIL: Snakes are mentioned over 80 times in the Bible and not one of them is positive. Make of that what you will.
