Xavier Samuel may be best known as Riley in Eclipse, but the Australian actor takes on a new challenge with a part in this month's period piece, Anonymous. The movie explores the mystery behind Shakespeare and happens to costar one of Xavier's Twilight saga cohorts, Jamie Campbell Bower. During our talk, Xavier told a funny story about a case of mistaken identity involving him, his little brother, and Jamie, and also weighed in on what he's looking forward to seeing on screen in Breaking Dawn. He even admitted to playing one of the female characters in A Midsummer's Night Dream during his college days. Check out our interview to hear Xavier's story, and be sure to catch Anonymous when it hits theaters on Oct. 28!
