Many good titles were mentioned here. So as not to add to the repetition, I will add some obscure, but I think fun-to-watch, movies:

• Death Machine (1994)
• Disturbed (1990)
• Dark Angel (1990)
• Tromeo and Juliet (1996)
• Mind Ripper (1995)
• Swamp Thing (1982)
• Stuck on You (1983)
• Brain Donors (1992)
• Wedlock (1991)
• Blind Fury (1989)

This reminds me of a certain Star Trek TNG episode titled “The Arsenal of Freedom”. Especially one specific moment of the episode: https://www.youtube.com/watch?v=kmDm8MVhZiQ&t=148s
