Continuity mistake: In the beginning, as Nielsen plays his violin you can see a quiver on his back, the next scene it is gone.
Continuity mistake: When Jacquouille gets frightened by the television set, he throws a statue in it, making the TV set explode. The blankets placed over the couches as well as various objects are sucked into the set. In the next shot, the couch right in front of the TV is still covered by its blanket, which disappears in the following shot.
Other mistake: During the rigged card game, the angle at which the hidden camera is shown would not have supplied a picture with the view from behind Eddy's shoulder, as is shown on the screen.
Continuity mistake: In the tanker, the girl and the CIA guy are bound to the chairs. When the tanker is jolted and every person gets pushed away, the girl's hands come loose, as her chair is thrown. Yet in the next shot both her hands are tied again.
Continuity mistake: The final game is reported by the ESPN announcer as being the "Inaugural Bourbon Bowl", meaning it's the first one. Later, on Bobby Boucher's jersey, there is a patch that says "Bourbon Bowl 50th Anniversary 1948-1998".
Continuity mistake: While the hitmen are kidnapping Nishi's daughter, we see her and her boyfriend in the back of the limo. As the boyfriend is trying to undress her we see that she is wearing ordinary white knickers.

Factual error: Even though Pops is in such bad shape that he needs a heart transplant, he isn't hooked up to any monitors or equipment while in the hospital.
Factual error: Dean Martin always drank apple juice when he was on stage because it looked so much like scotch and water and he had to keep up his reputation of being a heavy drinker who forgets where he is.
Continuity mistake: Whale commits suicide by drowning himself in the pool. When Clayton pulls him out the color of Whale's suit changes from black to brownish, and vice versa when Clayton throws him back in. Varying degrees of wetness should not be the reason as he should be drenched too while he is lying at the poolside. (01:33:40)
Plot hole: Alain joins the Legion, goes through extensive training and eventually gets his photograph taken. That's how Galgani recognises him and sends two men to kill him. They arrive with a platoon at the fort just after Alain, Mackintosh and Luther. The photograph would have taken a while to get back to France and then the two men would have to go through the same training. So how do they both end up in the same fortress after they joined the legion long after Alain?

Factual error: About 20 minutes in when they are at some ball/dance thing, Shakespeare's talking with a musician holding a lute. You can see fret markers on the fretboard of his lute, but these were not used on instruments until the late 1800's, early 1900's, definitely not in Shakespeare's time. (00:27:20)
Continuity mistake: When Marcia Gay Harden is doing the final preparations for the party that night, she and Anthony Hopkins have a dialogue where they talk about favorites and children.

Continuity mistake: When Patch and his roommate are arguing about why he wanted Patch out of the college, the book on the desk changes to a very different looking book between shots - note the tabs and red-edged pages.
