Continuity mistake: During the bowling scene, Molly rolls a strike on the next-to-last lane. Bud then takes his turn immediately after, in the lane to the left of the one Molly just rolled a strike in. However it's clear there are still two pins standing in that next-to-last lane.
Continuity mistake: During the final debate scene when they show the two candidates on stage with the monitors behind them, the background on the screens does not match the background behind them at the camera angle used. You can see the rows of stars, but not the rest of the background which would be in line with their heads.
Continuity mistake: At the beginning of the movie, when Bud is taking his daughter to school, you see barren landscape out the back window of the truck. However, when they show a view out the driver's side there are big buildings, but when it quickly switches back to the rear window view there is nothing but land again.
Continuity mistake: The pile of eggs that Bud knocks over in the security video becomes noticeably smaller when the angle changes.
