You know them from movies like Atomic Blonde, Mad Max: Fury Road, Inside Llewyn Davis, and Ex Machina, but this weekend, Charlize Theron and Oscar Isaac will lend their voices to two creepy, kooky characters, namely Morticia and Gomez Addams of The Addams Family. With such extensive — and impressive — filmographies to their names, we thought it would be fun to see how well they know their own work, so we sat them down with excerpts from reviews of their previous movies and quizzed them. Check out the video to see how well they did, and to see Charlize Theron proclaim that she’s horrible at charades, as hard as that may be to believe.
