Write it into the script. I mean, I personally would go to see "Casino Royale" just to see and hear Craig singing, "All I want for Christmas is my two front teeth, my two front teeth, my two front teeth...."
I hope they actually use the footage of the accident if it's so "brilliant". Mel Gibson's good at it, but sometimes it's hard to fake pain.
"As the shaken star staggered backwards clutching his bleeding mouth, cameramen thought it was a brilliant piece of acting."
The movie is scheduled to be released Nov 16th, 2006. They better hurry.
