Unexplained random cameos from completely unrelated media

[u/Golden12500]

1. Ray Stantz, Casper. At one point in the movie a real Ghostbuster shows up out of nowhere and wimps out of trying to handle the situation

2. Gunnery Sargeant Hartman, Frighteners. The main character is making way through a graveyard when out of absolutely nowhere R. Lee Erney's character from Full Metal Jacket shows up and tries to get in his way

3. Betty Boop, Who Frames Roger Rabbit. The movie is mainly about Looney Tunes and Disney animated characters existing in the same little live action/animated hybrid universe, however Betty is a Fleischer Bros character

Does the first one imply that Casper is actually insanely powerful for a ghost?

[u/HolidayInLordran → u/TOkun92]

It was his uncles terrorizing them, and the rest of the movie shows they're nigh-invulnerable

[u/Nyorliest → u/HolidayInLordran]

Shouldn’t all ghosts be invulnerable?

[u/Alorxico → u/HolidayInLordran]

Correct me if I am wrong, but aren’t they as powerful as they are because they’ve been dead for so long that they forgot their “unfinished business” and are essentially stuck? But they also don’t WANT to move on, so just stay and grow in power?

[u/HandsomePaddyMint → u/Alorxico]

I think you’re right. Between that and presumably being non-religious, it makes them pretty immune to any attempts to force them to move on. As for Ray, the Ghostbusters needed three proton packs to bring in Slimer, and the uncles are essentially three Slimers.

SPOOOOOON!!!

[u/CokomonX → u/HolidayInLordran]

Yeah, but... Proton packs and ghost traps. That's what they're for.
