Sheen sinks his teeth into Frost role

As if getting the voice right wasn't enough. Playing the legendary TV interviewer David Frost for more than two years on stage and screen has left actor Michael Sheen needing dental work after jutting out his jaw for so long to impersonate the "piranha"-like interviewer. "I messed up the thing that attaches you gum to your lip and eventually needed dental work done on my jaw," Sheen told the Express.
