Factual error: When Roberts makes a deal with the Captain, he demands that the Captain grant liberty to both sections (i.e., the entire crew), leaving only Roberts and one enlisted man aboard as the deck watch. All U.S. Navy ships must have enough personnel aboard at all times to get the ship underway immediately, if necessary, which is why the crew is divided into watch sections.
Continuity mistake: When they are on the back porch, watch the Coke bottle. The level of the liquid in the bottle goes down, then up, then down, etc.
Continuity mistake: During the robbery, the taxi driven by Danny Green changes from an Austin to a Morris Oxford and back again. Both types are the same colour, but the Austin is the one with the rounded radiator grille, and the Oxford has a flat radiator.
Continuity mistake: Adelaide performs her first number and finds Nathan in her dressing room. There is a pink robe draped over the partition. Placement of this robe changes during the scene without being touched. (00:49:45 - 00:50:30)
Other mistake: The catapult on the battlements Jean uses to evict the castle guards is rather curious. First, there is neither a bow nor any torsion to 'power' the weapon, and secondly it just seems to cock itself, right after each shot. All that Jean does is pull the lever and none of her diminutive helpers stand by for any cocking work whenever the catapult arm is shown.
Continuity mistake: Right at the end, Shirley MacLaine's dress has a large spot that disappears in the following shot.
Continuity mistake: When Tom is running away from Uncle Pecos, he runs into the house and slams the door. When he slams the door, you can see the little door at the top has nothing on it, but in the next shot a handle has suddenly appeared.
Other mistake: Philip De Guard is the cartoon's layout artist, yet when we see his name in the opening credits, it is spelled "Phillip" instead of the usual "Philip."
Continuity mistake: When the Coyote attempts to capture the Road Runner for the first time, he is standing on a bare patch of pavement surrounded by the puddle of glue he is spreading. In the next shot, the Coyote is now standing on glue with no bare patch, and when he realises he is about to be hit by the truck, he is standing on bare pavement in middle of the glue puddle once again.
Continuity mistake: When Calvin Q. Calculus has invented the portable hole, he says "Eureka!" and you can that there is a beaker on the desk, but in the next shot the beaker has disappeared.
Continuity mistake: When the Gophers hear Elmer Fudd and the furniture salesman coming, they hide in the bottom drawer, but when Elmer drives home, the Gophers are now hiding in the second drawer down.
Continuity mistake: Park Ranger Donald is leading five bears to a cave, so they can hibernate for the winter. He finds a bear sleeping in a hammock and forces him to join the others. There should now be six bears but a seventh bear has appeared out of nowhere. Later in the cave, their number has grown to nine.
Continuity mistake: When the 21st century demolition man discovers the box containing the frog in the cornerstone at the end of the cartoon, the frog jumps out and you can behind the box there is a document. But when we see a close-up of the frog performing in the next shot, the background is now rubble identical to the first scene.
Continuity mistake: When Emperor Nero tells Yosemite Sam to get him a victim, you can see that Sam is holding a sword in his hand. In the next shot, the sword has gone and Sam is now holding a bugle, and when he is marching along with the legion, he is holding the sword again.
Continuity mistake: When Speedy is bowing to the other mice when he comes back, you can there are four Sombreros behind him, but after a quick cut to Sylvester, we return to Speedy and a flower appears from nowhere.
Continuity mistake: When the camera pans in on the audience at the start of the show, you can see that Granny is sitting next to Bugs and Daffy, but after a quick cut to Elmer, we return to Bugs and Daffy, and Granny has disappeared.
Continuity mistake: When Elmer is picking up the money and putting into the case, the dollar note next to Sylvester changes position between shots.
