CHRIS HEMSWORTH initially got into acting because he loved movies and TV . . . but also because his family didn’t have much money, and he had a dream of being able to pay off his parents’ house.

But he put too much pressure on himself, and he was really struggling before he landed the role of Thor in the Marvel movies.

He said, quote, “If I hadn’t taken it upon myself to take care of my family, I might have been more relaxed . . . I remember I had an audition right before Christmas one year, where things were not going good.  I’d stopped getting callbacks, and I was getting worse feedback.  I thought, ‘God, why did I do this?'”

His luck started turning, but he still lost “G.I. Joe: The Rise of the Cobra” to Channing Tatum . . . and the role of Gambit in theX-Men” movies to Taylor Kitsch.

He said, quote, “At the time, I was upset.  I was running out of money.  But if I played either of those characters, I wouldn’t have been able to play Thor.”

He was cast as Thor 10 years ago.  Since then he’s done seven Marvel movies, and had big roles in “The Cabin in the Woods”“Snow White and the Huntsman”, and in the upcoming “Men in Black: International”.
