Continuity mistake: When Phil is lying in the desert and Carol shows up, she kicks one of his face balls to him named Gary. When Phil catches Gary and places his hand on him in this shot, Gary's face is pointed up towards the sky. In the very next shot, as Phil is exclaiming his name, suddenly he has Gary facing him right on. (00:17:22)
Continuity mistake: When Carol goes to cross out the garbage pool grievance, she accidentally goes under the words "phil garbage" before going through the rest of the words. When it cuts back, you can see the line is now going through "phil garbage" and the red line underneath is gone.
Continuity mistake: When Phil 1 knocks the Jenga tower down, most of the rows fall down. But when the shot changes, the fallen tower is now more than 4 times the height.
Continuity mistake: When the Phils are playing Jenga, Phil 2 is taking a piece out and you see the top rows; 3 vertical. 3 horizontal. 1 vertical in the middle. The camera angle changes and the top is now 3 vertical. 2 horizontal (missing middle piece). 2 vertical (2 side pieces). The configuration goes back and forth depending on the camera angle.
The Elephant in the Room - S1-E2
Continuity mistake: When Phil storms out during dinner and comes back in, he closes the door (we even hear it latch). When he proposes to Carol, the door remains closed until after she says yes, then in one shot it is open and stays open, with no one touching it.
