Wanna see a lot of my blood? 31 stitches today. #PremiumRush is gonna be awesome :oD (caution gore) http://tumblr.com/x6denkdgp

He wrote this at his tumblr site:
My first real wreck today. Busted through the rear window of a cab. Luckily got my elbows up. Coulda been way worse. No, but it was my fault, I was going too fast. The director, Dave Koepp, was extremely concerned for my well-being, but I made him RECord the wound. Anyway, Premium Rush is gonna be awesome. Gratuitous ER footage to follow, stay tuned...
