Must see: Charlize plays a hilarious game of charades with Josh Hartnett

Charlize Theron appeared on the Tonight Show with Jimmy Fallon to promote her new comedy western, A Million Ways To Die in the West. True to Jimmy’s style, she was roped into a game of charades that was just too funny for words!

Appearing on the show with comedian Steve Higgins, Charlize soon found out she would be in a double team game of charades facing off against host Jimmy Fallon and a surprise guest - who turned out to be the adorable Josh Hartnett.

The zany group then took turns acting out popular phrases and film titles like “Godzilla” and “Game of Thrones”, with hilarious results!

We've really missed Josh and that cute haircut of his, but he really sucks at charades!

The best part (0:47) is when Charlize is told she’s up first and exclaims, "YOH!"

So it’s true: you can take the South African out of South Africa, but vice versa? Not so much.

Watch the chaos below:
