Continuity mistake: Ron brings the tray with the beverages, the "Naco" and the matching burritos. Depending on the angle, the paper which the nachos and taco rest on is propped differently against Ron's hand. (00:29:20)
Continuity mistake: Kim gives Athena her bag saying "I believe this is yours?" Ron in the background puts down the right hand - but in close-up, he's peeking from the wall with both hands on the edge. (00:28:50)
Continuity mistake: After surviving the breakfast drone, Kim's mom goes in her room to talk to her before school. Kim puts the pompoms in her bag, but the bag is turned opposite ways between shots. (00:09:40)
Continuity mistake: When Kim and Ron arrive late at their very short first lesson, Mr. Barkin is holding the portrait of Lady Whiskerboots with his right hand at a different height between shots. (00:18:30)
Continuity mistake: When Kim runs to catch the bus after saving the baby, the foliage shadows in the street in her side view don't match the illumination of the street in the long shot. (00:12:00)
Continuity mistake: Kim takes a selfie with herself, Ron and Athena on her phone. She hands back the phone to her using the left hand, which turns into the right at the cut. (00:30:10)
Continuity mistake: Kim scores in tryout; the ball bounces from the back of the net almost to the goal line, but it's in the corner of the net when Bonnie stands. (00:24:35)
Continuity mistake: When Kim parries a soccer ball thrown from who-knows-where, an extra is walking behind her, and is nowhere to be seen in the next shot. (00:16:55)
Continuity mistake: When the bell rings at the end of their first meeting with Barkin at homeroom, Ron and Kim get shoved aside by the same students twice. (00:19:10)
Continuity mistake: Kim's Grandma helps her up after she went down sparring Bo. Kim is lying in a different spot of the tatami than in close-up. (00:54:35)
Continuity mistake: At the beginning of the scene at Bueno Nacho, Athena has her hands alternately on and off the table. (00:29:00)
Other mistake: In the fight at the beginning of the movie, Kim bends over and launches her jet-pack towards the villains. Almost everyone falls down way before the jet comes anywhere near and/or receive no impact, but they are KO as if they took a rocket to the gut. (00:01:40)
Other mistake: When the two women with the baby walk to the stroller, the one with a vest who does not believe in acting has her arm down her side in the first shot, folded with the hand on her belly in the second. It's also worth noting that the stroller is supposedly being pulled closer by the grappling hook, but the rope is not in tension. (00:12:00)
