Futurama ( 1999 )

Continuity mistake: In the very beginning scene, where Fry and Leela are talking, there is an explosion. When some ceiling falls down there is one big bit and three small bits next to Leela's foot but then a few seconds later there is one big bit and a few small bits all in different places. (00:00:40)

Continuity mistake: When Leela looks in the box, the wall behind her is red, then blue when it cuts back, then red again, and finally blue as she enters the other universe. (00:05:10)

Continuity mistake: When Fry first takes the tangled Christmas lights out of the fake box, they are all red and blue. However, when the shot cuts outward to get a wider view, many of the lights have turned green.

Continuity mistake: Just as Hermes A is about to shoot the box into the sun, all the crew (A and B) shoot out into the airlock. However, Hermes B doesn't come out of the box and just appears in the pile. This is confirmed in the commentary.

Audio problem: When Hermes says "If I know parallel Hermes-1, HE'S IN THE SUN BY NOW!" and when Amy-A says "Is it a kind of hairspray?" their mouths don't match what they are saying.

Three Hundred Big Boys - S5-E11

Continuity mistake: Right before Leela dives into the whale tank, she drops her snorkel and mask, but when the shot pulls back, they've completely disappeared.

Three Hundred Big Boys - S5-E11

Continuity mistake: When Bender is being filmed stealing the cigar, we see the "robocop" showing the footage on his screen. In the wide angle you can see he has the siren on top of his head, then in the next shot it's suddenly not there. Then he actually raises it out of his head in the final angle.

Bend Her - S5-E13

Continuity mistake: When Bender is a "female" and is putting stuff in his locker, in one angle you can see a yellow item next to his pink handbag. Then in the wider angle, this item is gray.

Bend Her - S5-E13

Continuity mistake: Right at the end, Bender is smoking a cigar and says something like "Emotions should be hated." In the very next shot when he has stood up, the cigar has vanished from his hand and there isn't anywhere he would have put it down.

Obsoletely Fabulous - S5-E14

Continuity mistake: When Bender and the other obsolete robots are watching a snail crawl across the beach, the snail is shown to be in the center of the screen with the robots standing around. Cut to Bender inserting a CD in his mouth, it then goes back to showing the original angle, but the snail has suddenly disappeared, and not enough time has passed for it to have crawled all the way out of the shot. (00:12:10)

Obsoletely Fabulous - S5-E14

Continuity mistake: The "Cartridge Robot" never takes the "Introduction" tape out of his slot, but in the wider shot it's suddenly vanished.

Continuity mistake: Near the beginning the Professor and Hermes are hitting something in a crate. Then Hermes puts down his rake and it then it disappears. (00:02:10)

Continuity mistake: When Calculon is bathing in champagne with Monique there is a napkin or something behind her, but when the robot actor breaks down it is nowhere to be seen.

Continuity mistake: When Bender is auditioning there is a cup on Calculons table that appears and disappears between shots.

Continuity mistake: When Bender takes the Professor and the Network Executive's gun, in the close up he is facing the Professor but in the long shot he's facing the crew.

Other mistake: When Fry says "Hey Bender" 3 times he then picks up the phone and says "Hey Bender" but watch carefully and you'll see he doesn't pick up the phone he just reaches out and suddenly has it.
