Continuity mistake: When Joan walks onto the landing holding a pet bed she tells her father she's putting the bed in the guest room and you can see her hair is tied in a ponytail. However, when she then enters the room, her hair is now untied and down her shoulders. (00:21:11)
Visible crew/equipment: After the brief confrontation between Joan and her father, the shot faces towards a pair of framed photographs and the camera casts a very clear shadow on the mantle piece. (00:13:04)
Visible crew/equipment: As Rudy gets out of his car on the runway, after the plane carrying the animals has landed, you can briefly see a number of crew members reflected in his side mirror as he exits. (00:08:12)
Continuity mistake: Towards the end of the film we see a pizza boy attacked by the flying monkeys and in the struggle the front wheel of his bicycle is bent out of shape. However, later on when James and the Sheriff find the bike, the front wheel is now perfectly straight.
Continuity mistake: When Sheriff Flemings and James drive to the sugar mill the emergency lights on Flemings squad car change back and forth from blue/white to red/white between shots. (01:09:42)
Visible crew/equipment: When Sonya is getting ready to get in the shower there is a shot from inside the bathroom of her in her bedroom, if you watch the closet closest to the bathroom door you can see the shadow of a nearby crew member cast on it, moving around. (01:04:27)

Character mistake: When Sheriff Flemings arrives at the gas station murder scene, Deputy Baldridge is already there taking photographs. The pair exchange a few words and Baldridge says he can't find the victims body. The pair then look up to see three of the flying monkeys noisily eating Mr Sites corpse on the roof of the gas station. Apparently Baldridge didn't notice this the whole time he was there. (01:03:19)
Other mistake: When the title card "FLYING MONKEYS" appears on screen, during the opening fly-over shot, if you look near the bottom right of the screen you can see something briefly move into, then out of, shot. (00:02:28)

Character mistake: When Joan is searching the web looking for information on what monkeys eat, there is a section on the screen that reads "The diet of monkeys varies form fruits, leaves." Obviously the correct word for this sentence should be "from" not "form." (00:36:21)
