Kate Winslet recently dropped by the Intelligence Squared podcast and gave a nice shoutout to Eternal Sunshine's Clementine as one of her favourite, pivotal roles. Via Far Out Magazine:

“I think a favourite for me is Clementine from Eternal Sunshine of the Spotless Mind,” she began. “But you see, the period from Titanic till then, which is about six or seven years, that period of time, making those choices to do smaller films and take risks and be in things that sometimes barely even saw the light of day, I think all of that instinctive behaviour on my part as an actor in making those smaller choices, I think all of it paid off. So I think Clementine is probably one of my favourites, yeah.”

Written by the acclaimed Charlie Kaufman, Eternal Sunshine of the Spotless Mind is undoubtedly Winslet’s best film and it also features the best performance of her career. Unlike the period pieces she mostly featured in, this 2004 work of art conducts a surreal psychological examination of the nature of a romantic relationship. Kaufman won the Academy Award for his screenplay, and Winslet earned an Oscar nomination for Best Actress.

Winslet said, “It’s really fun to take risks and it’s really fun to play lots of different characters. Clementine was the most eccentric part that I’ve ever played. I just had so much fun doing her. What an unlikely pairing. I mean, you wouldn’t imagine that Jim Carrey and I would ever do a movie together.

“When I was sent the script and was asked to do it, I just thought, ‘Well, there’s no way I’m not going to do this’ because I knew that it would be a totally new experience and very challenging, which it was both of those things.” (Source)
