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.

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.
