Continuity mistake: During the first chase scene, the semi passes by an empty taxi cab and when the camera angle changes, the semi crashes into the same taxi cab. (00:06:05)
Continuity mistake: In the scene where Owen and Tom pull Dodger from the pool. We see that Dodger's hair is hanging down over her face. We then see Owen's reaction, and then we return to Dodger. This time we see that her hair is behind her ear. She didn't have the time and it wouldn't make sense that she changed the position of her hair.
Revealing mistake: When Jim hits the brakes in his stolen patrol car, the two pursuing police cars turn and flip over and over. As they roll, the 'roll cannon' is visible on the underside of one of the cars (a round steel tube in a hole in the floor) and at left, the two cannon slugs from both cars bounce down the road. This device fires the slug downward, and the force behind it lifts the car when the slug hits the road, launching the car over.
Revealing mistake: When Arnie jumps from the plane, notice the stunt double. He weighs about half of what Arnie would, and has no muscles. (00:55:10)
Factual error: When we first see Fatima Blush, she is waterskiing. She is doing several stunts, which are only possible with one ski, the most notable being skiing backwards with one foot in the air. However, when she releases the tow rope and skis up the ramp into James Bond's arms, she is on two skis. (00:45:55)
Continuity mistake: In the scene when Hannibal returns from Lecter Castle after the murder, his aunt is waiting for him in his home. In the close up of the aunt Hannibal's collar is up, in Hannibal's close up his collar is down. (01:05:15)

Continuity mistake: Before the wreath of garlic falls down on Lucy's bedside table, it can be seen hanging on the lamp, but in the previous shot, as well as earlier in the scene, there was no garlic on the lamp. When Lucy grabs the vase from the bedside table a couple of shots later, the garlic that fell down on the table has mysteriously disappeared. (01:09:35)
Continuity mistake: Sand has a mole on her left cheek. In her photo, in the locket that Denny gives her, this mole is missing. (00:24:20)

Continuity mistake: When Jeanie is telling Richie the order, she alternately holds the pad, or it is down on the table. The pencil in her hands disappears in one shot too. (00:07:15)
Continuity mistake: When Vernon is looking in the basement files and Carl walks in, the card in the drawer label holder is tilted and it stays this way for a few shots. When Vernon claims it's a highly sensitive area, the card is now straight, but in the shot after that it is tilted again.
Continuity mistake: Paul Kersey boards a bus where the line number reads 990. When he gets off, the number is 99. He could not have changed buses because the number of the bus itself remains 8027 throughout. (00:54:50)
Continuity mistake: There is a scene in which it is raining quite heavily and Em and Richard are inside the hutch. Richard is playing Pop Goes The Weasel over and over which annoys Em. She stabs him in the foot and he chases her outside. In this scene she is wearing a strapless dress but when he catches her and pins her down on the sand she is wearing a lacey jacket (she didn't have time to change) and there are no clouds or rain. The sand doesn't seem to be very wet either, despite the fact that it was raining heavily a few minutes ago. (00:41:10)
Revealing mistake: In the scene where King Arthur expounds on the joy of his kingdom, he has a Band-Aid on the back of his neck. (00:21:00)

Visible crew/equipment: When Gort picks up Patricia Neal next to the flying saucer, you can see cables leading down to her body to keep her hoisted. (01:20:15)
