Other mistake: After the crash landing in the desert, when the astronauts are preparing to head out on foot, Brubaker states that he will continue west, then tells Walker to go north, and Willis to go south. Brubaker heads out straight ahead, Walker goes to the left, and Willis to the right, meaning that Walker was actually going south, and Willis to the north. (01:04:40)
Other mistake: When Mel Brooks is singing the song "High Anxiety" to a bunch of people in the dining room, near the end of the song he sings about two words and his mouth is clearly not moving. (01:00:10)
Other mistake: While Bond is being escorted by some guards, he opens a crate full of gas tanks, and begins fighting the guards off. If you look behind Bond in a brief scene you can see a few yards away another guard who is clearly watching this happening yet doing absolutely nothing.
Other mistake: When Harry passes the house by mistake, and Fran points it out, they overshot by a long way. But he stops and reverses almost straight in front of the house and parks.
Other mistake: Guido runs over the brigand who just gunned down his woman (and that for some reason is eager to literally jump in front of the car despite being in perfect safety before). The car approaches the lorry driving on sunny asphalt already bearing in front of the car clear marks of the dangerous overtaking. In the next shot the marks are gone and so is the sun. (00:11:00)
