5. Iwan Rheon
If you remember Iwan Rheon from his fantastic turn as the withdrawn Simon on Misfits, it might be a little hard to imagine him singing in the spotlight. You might envision him as the type of actor who is committed to the craft but horribly shy, and goes off and lives in a cabin in the woods while he's not working. But the reality is quite the opposite: this Welsh actor seems to thrive as a live performer, and is quite a talented musician. He's like a handsome shark! In 2010, he won an Olivier Award for his performance of Moritz in Spring Awakening on the West End. Since that year, he's also recorded three solo albums, Changing Times, Tongue Tied, and Bang!Bang!. Maybe Game of Thrones could work in a musical number somewhere? Ramsay Snow definitely seems like the kind of guy who could get away with a maniacal version of Putting on the Ritz or Singin' in the Rain. No? Just me then? Alright.
