David Tennant's Sideburns!

Because that’s what you do as an actor, and I’ve done it for years, and you get used to it. But then of course you forget, and you get spoilt, because people…know who you are and give you stuff and you get very smug. And then you have to go out there again, and hustle. Which is always a bit embarassing, everyone’s sort of there thinking
‘I want you to Die.’
“Good Luck!”
‘Ooooh, you’re better looking than Me You Bastard’
“No! Break a Leg! Go On!”
