Before he became a larger-than-life hero of the Marvel cinematic universe, Chris Hemsworth was a young Australian soap opera star. When not wielding the hammer of Thor, the 39-year-old has starred in movies like The Huntsman, the Formula 1 driving film Rush, and, in a memorable turn to comedy, Ghostbusters.

Chris and Willie Geist got together in New York for a Sunday Sitdown.
