3. Stanley B. Herman - "Ass-To-Ass" Guy In Requiem For A Dream
The Role: A sleazy, lecherous older man who suggests that, at Marion's sex party, she go "ass-to-ass" with the other girl she's...engaged with.
Why It's Amazing: The scene is so filthy and dirty, yet this guy, with his enthusiastic expression and creepy delivery, somehow makes the scene feel all that much worse. He's developed quite the fanbase on YouTube, his IMDB board and Facebook over the years.
What Happened?: Herman has occasional, blink-and-you'll-miss-it appearances in movies and TV shows, notably Aronofsky's most recent film, Black Swan (amusingly credited as the same character, "Uncle Hank").
