In early 2010, Samuel was cast as Riley Biers in The Twilight Saga: Eclipse. The film gave Samuel his first blockbuster film worldwide. Samuel received his first award nomination and win at the 2011 MTV Movie Awards. In an interview with GQ Australia in November 2010, Samuel described the process of his shock Twilight casting. "I sent off the audition tape from Sydney, which landed in a big pile on someone's desk. So then to actually hear something back was kind of unusual. I guess I was a bit of a gamble, but it's bizarre and wonderful. "
