'Inception' star Joseph Gordon-Levitt has been injured in a crash on the set of his latest film.

According to a posting on the actor's blog, he was badly cut and required 31 stitches after crashing his bike into a taxi while filming for 'Premium Rush'.

Gordon-Levitt wrote in the blog: "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 (sic)."

"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."
