Continuity mistake: During Marty's drive to the bogus address, when he is done speaking with Monty, just as he says, "Wolf out!" he pulls the phone wire and the earpiece actually pops out of his ear, but in all of the following shots that earpiece is still in his ear. Since the super-glued earpiece is one of the main plot points, this is bizarre to say the least. (00:44:25)Super Grover
Continuity mistake: In the scene where Jason's parents arrive at the airport in Los Angeles his mother is wearing a brown jacket. It remains brown until the scene where Jason meets his parents at the set and his mother's jacket is maroon. While she has more than enough offscreen time to change jackets, she does not have a jacket to change into (they are driven straight there) and no reason to change the jacket.
Visible crew/equipment: In the first step of phase four, after Frank's limo has "stalled", when Jaleel drives off with Marty who shouts, "Sayonara, loser," in the next shot and two shots later the reflections of a crewmember (wearing shorts) running backwards, other crewmembers, the boom mic, camera and equipment are all visible on the limo's surface.

Factual error: The amount of dye from the bottle couldn't possibly make Marty's entire skin that deep a shade of blue.
Continuity mistake: At the premiere of Marty's failed movie, he is asking the president if he can explain his "breakthrough" on Big Fat Liar. The president raises his hand, and says "One chance, Wolf, that's all I'm giving you." It remains raised until two shots later (on Marty's line "strap on your seatbelt because you are about to be blown away,"), when it is suddenly resting at his side.Movie_Freak 1
Continuity mistake: Jason and Kaylee arrive in LA on Thursday, and phase one begins Friday morning, but during 'phase one: surveillance day', when Jason and Kaylee are at the stunt demo, Jason looks at Marty's iPAQ PDA and the date reads Sunday, June 4th (stunt demo noted between 12:30 and 1:30pm). Yet, when Vince, the stunt coordinator, tells Marty that he's taking the next day off (day of 'phase two') to take his granddaughter to a birthday party, the clown invitation notes July 28th as the day of the party. Then, on Saturday 'phase two: the take down', when Jason is seated at the bus stop he looks at Marty's PDA and the date reads June 22nd, the day of the 'Whitaker and Fowl' premiere and party. Go figure... (00:35:50 - 00:52:40)Super Grover
Continuity mistake: When Marty is talking to the studio's president about his 'incredible breakthrough' about BFL, Monty has her head leaned up against a chair. Marty continues talking when the camera cuts to a close-up of Monty. With no time in between shots to move her head, her head moves about 6 inches away from the chair.
Continuity mistake: At the very end, during the credits of Jason's 'Big Fat Liar' premiere, you can see Jason's mom over his shoulder wearing a spaghetti strap dress with a shawl around her shoulders. The shawl moves on and off her shoulder between shots.
