Its kind of like the 6 degrees of kevin bacon.
Kevin Spacey was in American Beauty, with Wes Bently. Wes Bently was in ghost rider as Blackheart. Kevin Spacey also played Lex Luthor in Superman Returns.
In the movie American Beauty, the two above scenes were depicted, slightly differently, kevin spacey the downtrodden suburban husband whos trying to break free, spends a bit of time outside a fancy party his wifes at, with the new neighbor kid (wes bently) smoking pot talking about Re-Animator.
The other is the end of the movie, and this is spoilers for folks so beware, in which Kevin now realizing all he needs and loves in the world is his family and is finally "at peace" with his life in a way, is then shot in the back of the head by the neighbor kids dad who had a bit of a sexual orientation questioning problem and had attempted to kiss kevin spacey earlier and kevin sort of politely brushed him off what not.
Essentially its taking characters from other movies played by actors in that movie, and having htem depicted as those characters in this movie.
Hope that clarifies.
