During the monthly mothers' meeting at the Walkers' house, CC and Wyatt create a mess in the kitchen trying to prepare some food. Then they serve it and immediately leave the house. When the family returns, the kitchen is completely clean and tidy.
As Wyatt is having his interview, he flips the chair around so the back of the chair is facing the interview panel, and he sits in the backwards chair. The interview panel asks if this is Flashdance, and the camera cuts back to Wyatt who is now sitting in the chair normally. There was not enough time for him to stand up, rotate the chair and sit back down nor was there any noise to indicate he moved the chair.
Everyone wakes up switched, woken from bed, but comes downstairs and the baby is in the high hair. If they all just woke up, who put the baby in the highchair?
When Bill is having his Yale interview in the body of Wyatt, he turns the chair and sits down. One of the interviewers says "Is this Flashdance?", but right in the next shot when we see the room from outside, he is sitting in the chair, which has magically been turned around to its original position and Bill sitting comfortably on it.
CC could not be called up to the national US soccer team in the manner portrayed. This is an honor only really provided to the highest level professionals. Given the implicit skill level, she could potentially be called to the under 18 squad, but even then it would be a short term and seasonal honor, not a job you move away permanently for.
A better/more likely scenario would have been the classic college scholarship route, or a local pro team coming seeking to sign her.
The aligned planets as seen in the night sky are far too bright and far too close together as seen in the telescope.
The venue of CC's soccer game is BMO Stadium. The announcer announces this as B-M-O but it is actually pronounced as B-Mo, for Bank of Montreal.
Wyatt is portrayed as a science genius yet when describing the planetary alignment he also uses the terms "galactic" and "interstellar" which both relate to things outside the solar system. He should have said planetary or interplanetary.
