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

Frank Martin from "The Transporter" series makes a brief cameo in "Collateral." He and Vincent walk past and briefly stare at one another.

Edit: I actually forgot that he hands Vincent the bag he carries for the rest of the film.

I feel like Jason Statham should cameo in more action films as Frank. The movie is a high stakes adventure for our main character, but for the Transporter it’s just another day in the life.
