Well, you might get a pass for The Truman Show.. But he's amazing here, opposite the amazingly enticing Kate Winslet, in an ironically unforgettable film.
The basic premise of the film is that the two main characters recently went through a messy break up. Thanks to a strange new technology, Clementine (Winslet) decides that she wants to undergo a procedure to remove Joel (Carrey) from her memory completely, and Joel struggles with the reality of removing Clementine from his life. Explaining more would really ruin the plot and how it unfolds. Essentially it's a love story that explores the ideas of fate and the highs and lows of life. If you take anything away from it, it should be the thought about whether, given the opportunity, you'd choose to simply erase all the bad things that have ever happened to you, and if it would be worth it.
Seriously, I can't recommend the film enough. Out of all the films I've posted about in this topic, this is the one to see.
