Before he became an in-demand film star, Murphy was one of the world's top comics and could fill huge venues, like New York's Madison Square Garden - and now he admits he's itching to get back out there.
The Shrek Forever After star says, "Within the last six months or so, I started getting an itch to do it again. I started writing stuff... I was like, 'I could go and do 15, 20 minutes right now. Maybe in a couple of months I'll start working out again.'
"But it'll take a year before I'm ready to go on the road... It's gonna take at least a year to get the rust off; 20 years of rust."
