Here’s a pic of Mark Hamill with Corvette Summer co-star Kim Milford (left), at the Las Vegas Hilton circa July 1977. I don’t know who the other 2 people in the photo are, but Mark looks like he’s being held hostage.
Cool to think I was actually living in Las Vegas when this photo was taken!
Here’s the article that the photo came from:

Kim was probably talking Mark’s ear off about how Laserblast was going to be bigger than Star Wars. 😉
