Touched By Twiligth has an amazing interview with Michael Welch, who plays Mike in Twilight.

The scene in the diner, with Mike dancing outside the window… improv or scripted? Were you encouraged to improve or did you have to stick straight to the script?

There was a lot of improve in this film for the humans (Eric, Tyler, Angela, Jessica, and Me). Catherine didn’t really care whether dialogue or actions were improvised or scripted, or whether ideas came from her or the cast.

In the case of the diner, the process went like this… The script said something like, “Mike waves and calls out, trying to get Bella’s attention.” Catherine showed me where this will take place, suggested a couple of ideas, and ultimately left it up to me to come up with something that works. I thought of that dance (for whatever reason), showed her, and she approved. Later in post-production, she had me come into a sound studio to record some various, “Bow chicka WOW wow. WOO WOOO!” whacky noises. She picks one of three choices, and there you have it. Mike Newton in all his goofy glory, dancing for the affections of Bella.
