Since we're talking about TV and movies, today's prompt follows right in line. Take one of your stories/novels and write out your fantasy cast list. Since it's a fantasy list, your dream actors don't need to be their real-life ages, or even alive. So, if you think Marlon Brando, age 32, would make the perfect John Smith, plug him right in there.
The goal here is to spend some time thinking about character, as well as thinking about which aspects of your characters would translate the best to screen.
Extra credit for those who share their cast lists ;)
