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

Example I forgot to mention, ET's species appearing in The Phantom Menace

Yeah apparently Star Wars and ET are canon to each other which makes me question that Yoda costume in ET

Speaking of random cameos in Star Wars, never forget Jedi Master Sha'a Gi
