Charlize Theron is one of our favorite actresses. She’s currently busy doing press for her new movie, Tully, which hits theaters on Friday, May 4th. Theron has been candid about her 50-pound weight gain for the role of Marlo, a mom to two young kids and a newborn. But that’s not all she’s been talking about in interviews.

During a recent appearance on The Late Show with Stephen Colbert, when the topic turned to Tom Hanks movies, Theron opened up about a terrible audition she had for the 1996 Tom Hanks movie That Thing You Do! She got the part, but it turns out that her audition did not go well.

“It was not good. I don’t know why he gave me the role. I was so nervous. I mean, imagine you’re 19 and you meet this idol. I idolized him. I watched Turner & Hooch like, 500 times,” Theron told Colbert of the audition. “So to audition for somebody like that is frightening.”

What made the audition so bad? Theron kept fumbling her words.

Unsurprisingly, Hanks was extremely nice about Theron’s nerves.

Watch Charlize Theron tell the full story below.

It begins at the four-minute mark. Her facial expressions are priceless.

No worries, Charlize. Everything worked out okay in the end. And we’re so glad that it did!
