Continuity mistake: Don whacks the alien crab on the roulette; the cards on the table are different between shots (there is a cluster of three cards that is on the left, then on the right of the dead beast, for instance). (01:03:50)
Continuity mistake: Don swings the golf club at the creature on the bar; the stewardess ducks behind the counter and starts scurrying away. The creature jumps away, but in the next shot the bug jumps up her wazoo while she is standing and facing the counter. She couldn't be in that spot and in that position this fast. (01:04:15)
Continuity mistake: After being violated in bizarre fashion, Janet slumps to the floor. Her dead body rests on the floor in a different position (arm on chest) just after. (01:05:10)
Continuity mistake: The rich guy keeps putting stacks of money inside the briefcase, but it never fills up, with gaps appearing at the cut in spots he previously filled. (01:08:25)
Continuity mistake: After the alien attack, the hole on the rich guy's forehead changes size between shots. (01:08:35)
Continuity mistake: Don and the others find the corpse lying face down into the money. The larger bloodstains are faithfully rendered from one shot to the next, but the bills and the actor's hand have changed position. (01:09:00)
