Character mistake: Considering she was wearing heeled boots, Ms. Underwood should have either taken her shoes off or at least have had a carpet provided to her if she was going to sing on the competition mat, as her shoes could have torn it. Other than emergency medical professionals, anyone who is going to step on the mat should remove their footwear.

Cobra Kai (2018)
1 character mistake - chronological order
Starring: Ralph Macchio, William Zabka, Courtney Henggeler, Xolo Mariduena
Other mistake: Hawk gets a mohawk, but his hair was too short to style it like that.
Suggested correction: The mohawk was not a prop, but the actual hair of the actor they shaved off and mended together for him.
That is true, it was the actor's actual hair, but in the realm of the show, Eli's hair was not long enough to style that large of a mohawk out of it.
Johnny Lawrence: Robby. What's going on?
Robby Keene: I followed you.
Johnny Lawrence: What happened here?
Robby Keene: We're moving to a new location. Multiple locations, I think.
Johnny Lawrence: You kicked ass today. It could've gone either way.
Robby Keene: Yeah. Thanks.
Johnny Lawrence: Hey, it's just a match. Don't let it eat you up, trust me.
Robby Keene: It's not that, um, it's this kid, Kenny. I thought I could take him under my wing, be the mentor I wish I'd had when I was younger. When I saw him today it, uh, it was like looking in a mirror. And I realised I screwed everything up. And I had all this hate inside of me for you and for Miguel. And I thought I could use Cobra Kai to control that. But it just made things worse and now it's never going to get better.
Johnny Lawrence: That's not true. You had a good thing going with LaRusso. I got in the way of that. Don't blame yourself, you blame me.
Robby Keene: I'm sick of blaming you, Dad.
Trivia: The book that Sam reads is The Outsiders, Ralph Macchio starred in the film version.
