Continuity: In the scene where Fletcher is in his office and he's trying to write that the pen isn't blue, he swipes everything from his desk and there's then an overhead shot showing the only thing left on his desk is a small piece of white paper on the right hand side.

Continuity: The gift changes position from when Gretta holds it to when Fletcher takes it away. (Time)

Deliberate "mistake": When Jim Carrey is chasing the plane with the flight of stairs, he is able to catch up to it. The guy who fixed it must of been one hell of a mechanic because most flights of stairs don't go over ten miles per hour, while most planes get up to 50 miles per hour when taxiing.

Other: When Jim Carrey is attempting to force himself to write the word "red" on his desk, in the shot before the "blue." is revealed, his pen is not even touching the desk and his final pen movement is a curve which doesn't correspond to an exclamation point.

Continuity: Towards the end, Fletcher is on the stretcher talking to Max, and looks at his watch to discover he has been able to lie for half an hour. Max then responds "So you lied?". Fletcher then grabs Max's shoulder with his left hand, saying "No! It was the truth!". As the angle changes he is still speaking, but his left hand is now lying across his chest before he reaches out to grab Max again. Submitted by Twotall

Then it shows a back view of Fletcher speeding away and his sunglasses are gone.

Continuity: Just after Fletcher steals the yellow airfreshener from the car yard, he has his arms by his side. When the shot switches back to him, he has his arm on the counter.
