I’m sorry, I’m very squeamish and don’t want to look this up, but I have to know along what plane he was cut in half, like left to right, front to back, or top to bottom?
My stupid brain always associates the name Thirteen Ghosts with Venom (2005) and I only realized why just now, when I looked up the latter:
Summary:
A group of teenagers fear for their lives in the swamps of Louisiana, chased by Mr. Jangles, a man possessed by 13 evil souls, and now relentless in his pursuit of new victims.
I only saw Venom once when I was way too young and it has its own neural pathway.
Bonus: I found Venom by searching "horror movie truck snake demon" because that's the imagery that automatically pops into my head alongside Thirteen Ghosts. It's the first result.
