'Eternal Sunshine of the Spotless Mind' turns 20! Jim Carrey and Kate Winslet sat down with ET in 2004 to chat about their on-screen chemistry in the cult classic romantic comedy. Jim explains why Kate is 'feisty' in her role as the impulsive yet charming Clementine Kruczynski. Plus, Kate shares what it's like to play the spontaneous character opposite of Jim, who uncharacteristically plays the role of the quiet, reserved Joel Barish.
