Continuity mistake: Wick takes the lapel pin off and places it in his right front jacket pocket. Shortly afterwards he takes it out of his front left jacket pocket. (00:49:10 - 00:56:20)

Movie Medic

Factual error: Amongst the essential parts of a nuclear weapon's detonation mechanism is a radioactive isotope of tritium, which has a half life of just 12 1/2 years. The tritium in every nuke on earth has to be replaced every ten years or so. This is by no means unusual; there are other perishable parts including detonators made of conventional explosives which would be completely inert after a thousand years. After lying dormant with no maintenance at all for that amount of time the nuclear weapons the 'Man-animals' find would be big shiny paperweights and not much else.

Visible crew/equipment: As Will and Jack duel up top in Brown's shop, in two close-up shots a large plank is visible at their feet with two long black marks along each side detailing where the beams are supposed to be, so that Orlando Bloom and Johnny Depp know where to land as they supposedly leap from beam to beam and feign keeping their balance. (This is ONLY visible on the video version.)

The Thrice Cream Man/The Flibber-Flabber Diet - S1-E7

Other mistake: In "The Flibber-Flabber Diet," Chowder and Truffles return when Mung calls them. How could they hear him when they'd already left?

Other mistake: On one of the SHIELD monitors, "perimeter" is spelled "perimiter".

LizzieWD

Continuity mistake: When Finn is going to an escape pod to run away, he puts his pack down in front of it, seen again in a later shot. When Rose realises he's trying to run away, his pack has moved itself inside the pod.

Awesomolocity

Trivia: Have a close look at the Predator's trophy collection on his spaceship. Taking pride of place is a skull from the creature in the Alien movies. (01:33:05)

Continuity mistake: When Mrs. Otterton is in Chief Bogo's office holding her family photo with both paws, in the wideshots her purse is hanging in the crook of her left arm, but after a brief shot of Judy, when it cuts to Mrs. Otterton's closeup as she tells Bogo about her two beautiful children her purse is gone, then after another brief shot of Judy the purse is back in its place again in the wideshot.

Super Grover ★

Continuity mistake: Near the end of the movie when the 'false' Buzz Light Year is running along the air conditioning ducts his 'New Utility Belt' disappears then reappears again. (01:01:55)

Isabella Swan: Everyone's staring.
Edward Cullen: No, not that guy. Oh wait, he looked.

Question: Several other answers and corrections state that the reddish liquid sprayed by the tripods was what essentially grew the red vines. However I thought I heard someone in the film say something along the lines of "using us (i.e. blood) as fertiliser". Can someone please clarify?
