Actress Soo Hyun (Claudia Kim) talked about acting in movie 'Avengers 2' during an interview with Sports Today on April 27, revealing she had to ad-lib a lot of her parts!

She said, "In the script, it only said, 'Dr. Cho speaks in Korean.' �No one wrote the Korean lines and there was no one to help me on set."� Hmm, at what parts did they decide it was needed for her to speak some Korean to advance the conversation without having an actual, specific line in mind?

Anyway, she continued, "Depending on the atmosphere, I would personally insert lines in the Korean language. �I was more nervous about those parts than my English lines. �I worried that I might say something wrong."

You can see for yourself how well she does as the movie is set to hit American theaters on May 1!
