Revealing mistake: Ron leans against a barrel and sets in motion a series of events leading to an explosion. For being able to tip it with such a modest push, it is obvious it was empty (confirmed also by how it bounces). (00:02:20)
Kim Possible (2019)
1 revealing mistake
Directed by: Adam B. Stein, Zach Lipovsky
Starring: Sadie Stanley, Sean Giambrone, Ciara Riley Wilson, Todd Stashwick
Character mistake: It's merely training, but her opponents are hostile and want to exclude her from playing, so it's funny then that they don't call Kim out for her actions being egregious fouls; she brings the ball trapping it between her feet in multiple cartwheels (you can't just hold the ball between your feet for prolonged amount of times and 'carry' it). You could also say she kicks the ball at an opponent's face on purpose, which is equally unsporting. (00:24:00)
Trivia: When Kim throws a henchman over the railings onto Professor Dementor, the henchman lets out a Wilhelm scream.
