Visible crew/equipment: As soon as Marion gets locked in the cockpit of the Nazi plane, you can see a crew, a blue van, a ladder, and a man with a white sleeveless shirt and a big brimmed hat all in the reflection of the glass.

Revealing: While Indy and Marion are in the Well of the Souls, and they encounter the snakes, Indy falls to the ground only to get confronted by a Cobra rearing its head and hissing. Look carefully and you'll see the reflection of the snake on the safety glass between it and Indy. Briefly you can also see the torch's reflection while he's waving it around. [This has been corrected in the new DVD set. You can only see it if you have the original VHS. I think it's visible in the "making of" on the DVD as well.]

Continuity: When Indy and Sallah visit the gentleman who translates the staff headpiece for them we hear the staff should be "...six cadams (spelling) high."  Indy replies, "That's about six feet." Then, turning the headpiece over, "Wait - take back one cadam to honor the God of Israel..." So, about five feet now, right?   But, when Indy goes to the map room the staff is much taller than him.  If the staff is about five feet high, Indy would be around three feet tall.

Plot hole: What are all these German soldiers doing in British controlled Egypt prior to World War II. Appeasement aside, I think that the British might be a little worried about a large group of armed Germans being in a League of Nations mandated British Protectorate!

Continuity: When Indy is climbing into the map room, he throws the staff of Ra down the hole, yet when he climbs down, it's resting perfectly against the wall, as if someone had placed it there.

Continuity: Near the beginning of the movie where Indiana is running away from the tribe of South American Indians after Belloq robs Indiana of the gold statue, in one shot you can see that the Indians are only a few meters behind Indiana, but in the next shot, they are at least 50 meters behind.

Audio problem: When Marion and Belloq are getting ready to have a drink, as Belloq pours the wine you can hear the sound of the wine hitting ice, making a crackling sound, but there is no ice in the glasses.

Visible crew/equipment: After Marion goes in the basket, there is a chase and a truck tips over, if you look amidst the dust, you can see the ram used to put the vehicle on its side.

Revealing: When Marion falls in the Well of Souls, a snake jumps to bite her, but hits the protection window. Its reflection is also visible. Submitted by Dr Wilson

Continuity: When Indy goes to save Marion in the tent he removes the handkerchief gag. But when he decides to leave her there, he puts the gag back on and some of her hair gets caught underneath the gag on one close up shot from the left. But when the camera goes to the back of Indy, her hair is no longer caught underneath the gag.

Factual error: In the scene where Indiana Jones ambushes the Nazis with the Ark, he threatens them with an anti-tank rocket. Anti-tank rockets weren't developed until later on (well into the Second World War), and those very first, called "Panzerfaust", looked completely different. The type of anti-tank rocket he uses to threaten with is modern, dating back to the 70s.

Visible crew/equipment: After Marion supposedly dies in the truck explosion and Indy is drinking outside at the bar, watch to the left of him. You can see a man wearing a modern t-shirt and jeans walking through the crowd.

Factual error: During the travel to Nepal, "Thailand" is written on the map. The country has had this name only since 1939. This film takes place in 1936, when Thailand was called Siam. Submitted by Dr Wilson

Continuity: Just after Indiana (barely) escapes the tumbling boulder at the beginning of the movie, he leaps through a veil of spider webs, only to be held up by the native hunters and Belloq, who takes the idol from Indiana. Watch carefully - there is a thick strand of webs attached to the idol as Indy hands it to Belloq, but they disappear in the next shot as Belloq hefts the idol and holds it up in the air.

Revealing: In the scene where 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).

Other: When Indy is fighting the big German at the base of the airplane, Indy reaches down and grabs a handful of sand to throw in his face. You can see the finger marks in the sand from a previous take. Submitted by Lynette Carrington

Visible crew/equipment: 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.

Visible crew/equipment: As they come out of the "mapping room" in the tomb, there is an extra crouched down by the door, apparently hiding. It seems as if it was a quick fix for someone who was where they weren't supposed to be.

Continuity: In the scene where Indiana is fighting the Big German mechanic by the plane, the plane goes around in circles and the wing tip of the plane punctures a hole in a petrol tanker that is parked near by. This causes the petrol to gush out of the tanker and you can see that ground underneath the plane gets totally drenched with petrol. But in the later shots, the ground under the plane is dry. There is also a shot where you can see the tanker in the background not pouring petrol any more and all you can see is a little wet spot around the tanker.

Continuity: After Indy rips a big strip of Marion's dress in the Well of Souls, it continues to change until she finally gets rid of it on the boat. At some points (eg. running from the plane before it explodes, and other shots) it seems quite straight across, more like a shorter dress than a torn one. A few moments later, when they are crouching behind an earth bank and Sallah tells Indy the Germans are putting the Ark on to a truck, the dress is badly ripped in various places across her back. Not long afterwards, it is in one piece again but back to the bottom edge being ripped.
