Clint Eastwood
Clint Eastwood's distinguished film career began in 1955. Eastwood got his first big break playing an uncredited lab assistant named Jennings in Revenge of the Creature, the sequel to Creature from the Black Lagoon (1954). Eastwood's character is shown having a discussion with Professor Ferguson in which he accuses a test subject cat of having eaten a lab rat—before finding the rat in his lab coat pocket.
Mila Kunis
Did you know that American Psycho has a sequel? Well, Mila Kunis wishes you didn't. In 2002, Kunis appeared in her second-ever film role as protagonist Rachael Newman in American Psycho II: All American Girl, a stand-alone sequel to the original movie. American Psycho author Bret Easton denounced the film, and in 2005, Kunis expressed embarrassment over her role. "Please—somebody stop this," she said. "Write a petition. When I did the second one, I didn't know it would be 'American Psycho II.' It was supposed to be a different project, and it was re-edited, but, oh... I don't know. Bad."
