Revealing mistake: Billy is on the floor about to get attacked by Stripe. You can see the rip in Billy's jumper before Stripe has scratched him. (01:00:30)
Continuity mistake: Watch Billy after he has been first attacked by Stripe by a clawing to Billy's chest. He is wearing a sweater with a white T-shirt underneath. From that moment on the torn area of his sweater and the blood marking on the white T-shirt continuously change shape and size. And if Stripe's claws were sharp enough to cut him that badly, how come it didn't cut through his white t-shirt under his sweater? Because Billy showed a lot of pain when he was clawed. (01:01:55)
Other mistake: When the gremlin is using live wires to manipulate the traffic lights, the smoke goes in reverse, indicating a reverse footage shot. (01:05:55)
Visible crew/equipment: In the scene where the cop car flips over, if you pay attention, you can see the metal plate that's welded under the car that helps it flip over. (01:08:25)
Continuity mistake: Before Mrs. Deagle is attacked a portrait appears on her table between shots. (01:08:25)
Revealing mistake: When Mrs. Deagle is visited by Christmas caroling gremlins and one hot wires her chair, as she shoots up the chair, she passes the same pictures on the wall at least four times. (01:09:30)
Visible crew/equipment: In the bar, as one Gremlin bangs his beer glass on the table, you can see a wire attached to his arm, leading under the bar. (01:10:40)
Audio problem: When Kate is behind the bar, and the Gremlins are drinking beer and smoking, Kate says "Just don't bite me." Her mouth doesn't move at all when this is heard. (01:11:00)
Continuity mistake: When Billy turns to Kate, because she says "Now I have another reason to hate Christmas", he is holding a flashlight up by his chest, yet when the shot changes he is holding it down much lower. (01:15:45)
Revealing mistake: When a Gremlin shoots Kate, the glass is already shattered before the bullet hits it. (01:17:15)
Continuity mistake: Kate has a bruise on her right cheek near the end. When Billy tells her all the Gremlins are in the theatre and she says "All of them," her bruise is on her left cheek for the one shot. (01:19:25)
Continuity mistake: When Billy smashes the Candy store window the amount of stuff behind the glass changes between shots. (01:27:50)
Visible crew/equipment: When Stripe is attacking Billy with the chainsaw, when the camera pans to the side right before Stripe attacks you can see a crew member's hand place Stripe over Billy. Also you will notice that there is a piece of plywood attached to Stripe's feet. (01:29:10 - 01:32:55)
Continuity mistake: A pair of baseballs and several cans appear behind Billy when Stripe attacks him with a chainsaw. (01:32:35)
Revealing mistake: When Stripe is dying from the sunlight exposure, in some of the shots you can see his puppet strings (especially visible on Blu-Ray). (01:36:35 - 01:37:20)
Continuity mistake: When the movie ends, the sling around Billy's neck is either over the collar or under, depending on the shot. (01:38:35)
Continuity mistake: When the old man is leaving the family's home, in the indoors shot as he turns to walk out the front door, he is holding Gizmo's box under his right arm, and has the "smokeless ashtray" in his left hand. Cut to the outside shot of him walking through the door, and he is suddenly holding the Mogwai box by it's handle, and has nothing in his left hand. (01:42:00)
Continuity mistake: When Billy discovers Barney the dog wrapped up and hanging by the Christmas lights, Barney's face is pointed towards the house, but when the shot changes to Billy helping Barney down, the dog's face is turned away from the house.
Continuity mistake: When the gremlins are attacking Billy's mom in the kitchen, the kitchen is well lit with a window that allows sunlight into the room, but when Billy arrives at the house it's suddenly night time.
Continuity mistake: The first night in Billy's room, Gizmo is half a meter away from the Santa Claus hat, but when the angle changes he is just a couple centimeters away.
Chosen answer: The precise cut-off point is never stated - I've generally assumed that the embargo on feeding finishes once the sun comes up.
