Continuity mistake: At the beginning of the Truck Chase, when Billy Horrigan starts shooting at Indy, Reg Harding's right hand goes from grabbing the front passenger seat to grabbing the metal bar of the jeep between shots. (01:23:28)
Continuity mistake: When Indy is chasing after the truck on horseback, he jumps off the horse and onto the truck, as he does this the horse begins to slow down and fall behind, but as Indy throws the German soldier in the passenger seat out of the truck the horse has disappeared, it could not have been hidden from view behind the truck, because the horse's shadow would have been visible. (01:23:30)
Continuity mistake: When Indy is fighting the Nazis on the truck, one Nazi is thrown from the truck and is rolling the opposite direction of the truck. (01:23:30)
Visible crew/equipment: At the beginning of the ark chase sequence, Indy jumps into a truck off a horse and fights the driver. He pushes the driver up against the door. At the bottom of the frame you can see the camera shadow. (01:23:35)
Continuity mistake: Several times during the fight in and around the truck the bars around the top of the cab come off and are miraculously back on again. (01:24:05)
Continuity mistake: When Indy throws Terry Leonard out of the truck, the forest they were driving through disappears. Then Indy closes the truck's door and the forest reappears. (01:24:22)
Continuity mistake: Just as Indy crashes Gobler's jeep for the second time, you can see that beside the desert road is a large forest. However, the jeep falls off a cliff that appears out of nowhere. (01:25:37)
Continuity mistake: When the camera shows the back of the truck, there are two soldiers on each side of the truck, plus the sergeant inside it. As there were seven soldiers and one of them fell off the truck - there's a missing soldier in the scene. (01:25:50)
Continuity mistake: As the Nazis are preparing to leave Tanis, a soldier fires a shot into the air, causing several Arabs to fall to the ground and land in the middle of a circle of soldiers. In the next shot, as Belloq heads for the car, all the downed Arabs, the sergeant and the circle of soldiers have disappeared, with only the soldiers who were loading the Ark onto the truck remaining. (01:26:55)
Continuity mistake: As the sergeant climbs to the truck's roof, Belloq turns his head to watch the scene. In that shot, the staff car is passing next to a group of plants. In the next shot, almost all the plants have disappeared. (01:26:55)
Continuity mistake: While Indy is fighting the German who is driving the truck, you can see that the German has got blood on his left hand, but when he throws Indy through the windscreen his left hand is clean and there is no blood on it. (01:27:10)
Revealing mistake: When Indy goes through the windscreen in the scene where he is fighting the balding blonde German, the stunt double playing the German has a full head of brown hair. (01:27:10)
Continuity mistake: When the sergeant throws Indy out of the truck window, the adventurer grabs the Mercedes logo with his left hand. After two shots, he is to have let go. However, in the next shot, Indy is grabbing it again. (01:27:25)
Revealing mistake: When Indy fights the driver of the Nazi truck, the windshield is smashed when Indy is thrown through it, but there is no wind. Look at the driver's hair, not one stirs from a breeze while driving a fast moving truck with no windshield? (01:27:30)
Plot hole: When the sergeant takes control of the truck, Dietrich directs him to approach to crush Indy between the staff car and the truck, which takes time and allows Indy to make his famous scene. However, Dietrich could easily have shot him and arrived in Cairo with the Ark in his possession. (01:27:40)
Suggested correction: Shooting means risking hitting the truck's engine, which means finding new transport for the ark. All of which takes time off their schedule. Bad guys are always on a schedule.
True.
Revealing mistake: During the truck chase scene, Indiana is thrown or forced over the front of the bonnet and almost run over. There is a wide camera shot, and while holding on to the front fender, Indiana can be seen sitting on a chair which is attached to the truck. (01:27:40)
Revealing mistake: When Indy fights the driver of the Nazi truck, he gets thrown through the windshield, and eventually ends up underneath the truck. When he is climbing underneath the truck, heading towards the back of it, you can see the trench that was dug down the middle of the road to provide the stuntman (this being one of the few stunts that Ford didn't do himself) with the extra room needed to do this feat. (This is backed up by DVD commentary. The director stated that the truck was too low to the ground so they had to dig the trench in order for there to be enough room for the stuntman). (01:27:50)
Continuity mistake: When Indy runs over the sergeant, the background behind the truck changes between shots, going from the desert to a mountain. (01:28:45)
Revealing mistake: When the German staff car comes into the market place to find no truck, watch as Dietrich hurls the melon - the Gestapo guy in the front is obviously a dummy for this one shot. (01:29:40)
Revealing mistake: When we have the exterior shot of the ship that Harrison Ford, Karen Allen, and the Ark are aboard, specks of dirt can be seen over the view of the ship and the ocean - obviously, it was filmed through the window of another ship. (01:31:35)
