My dads brother visited us one time - when I was around 7 years old - and they sent me to bed and watched a movie together on TV. I’m not sure where my mom was, perhaps taking care of my little brother, but I quietly went down the stairs and saw them watching the movie, and I stayed very quietly so they would not know I’m there.
It was a Bruce Lee movie, “The Big Boss (1971)”. In that movie Bruce works at a ice factory and his boss kills some people and puts them into the ice. That’s not the worst of it. They then have those big ice blocks and a big blade saw and that saw cuts the big blocks into smaller peaces. It also cuts those bodies in the ice blocks into smaller pieces.
I couldn’t believe what I saw and went back upstairs and couldn’t fall asleep. I never told my parents.
Candyman, a mates older brother showed it to us when I was around 10ish, don’t think I was ever the same again.
Also caught a bit of Toxic Avenger on late evening tv around the same age, when I should have been asleep but sneaked on the tv. Boy did I regret that.
