Mistakes

When Lawler smacked Carrey off his chair in the David Letterman scene, the hit was so hard that it made Carrey's mouth bleed (you have to look very carefully). When he stands up and is shown close up again, the blood is gone. (Incidentally, the reason Lawler hit him so hard was that Carrey constantly stayed in character throughout filming, and taunted him relentlessly. Lawler decided he'd had enough.) See more...

Trivia

During filming, nobody was allowed to call Jim Carrey by his real name. Whether the camera was rolling or not, Carrey stayed in character, and everyone was instructed to address him as "Andy." See more...
