Continuity mistake: When Max sneaks up on the raider who's sitting at the wrecked dune buggy with the dying woman and man, look at the crossbow on the ground. At first it's unloaded. Then when the raider sees Max, he reaches for it and it's suddenly loaded and ready to fire.
Continuity mistake: When Snake kills the wrestler he falls forward shoulders forward, next minute his arms are over the ropes, next minute his arms are in a different position again - quite active for a dead man. (01:16:55 - 01:18:10)
Continuity mistake: When Indy is distracted by the young girl and her eyelid message, the girl changes from a window seat to another row when the bell rings to end class.
Visible crew/equipment: A stock car carrying Mel Tillis and Terry Bradshaw drove into a hotel swimming pool. If you watch the car as it drives into the pool, you'll see the jump ramp built at the end of the pool.
Continuity mistake: When Melina's car is hit by the machine gun, we see a close-up of the back end of the car, including the 2CV6 sign. Later in the car chase there suddenly is a Spanish national sticker (E) to the left of the 2CV6 sign. The bullet holes are different as well.
Factual error: The training set piece is supposedly Japan, but it's obviously taking place in the Philippines. Its biggest giveaway is the presence of Taal Volcano. (00:02:55)
