Visible crew/equipment: When Jamie Lee Curtis is leaving John Cleese's office, she kisses him goodbye and calls him Uncle.  After she has left, you can clearly see the cameraman move into view of the mirror.

Visible crew/equipment: When George enters Ken's apartment the first time and Wanda approaches him, if you look in the mirror you should be able to see a crouching crew member wearing a blue shirt.

Visible crew/equipment: After Ken kills the last dog and the witness has a heart attack, he walks out of the house he was in and in the reflection of the black door you can see a crew member and a camera.

Plot hole: Archie goes from being waist-deep in a barrel of oil to walking onto the airplane and sitting next to Wanda. She greets him, etc. But there's no oil on his pants, no logical question by Wanda: What the heck happened???

Continuity: When Ken lets the Doberman loose out of the back of the van, you see Ken looking through the rear window to watch the action. The camera angle changes and you no longer see Ken looking out of the window. The camera angle changes again and Ken is once again looking out of the window.

Continuity: When Ken has the bandage going round his head, both the bandage and the tape securing it - particularly the size and position of the tape strips, differ in consecutive shots throughout the scenes. One example is when Otto shares his chips with Ken and then enjoys his lovely little fish.

Continuity: When Wanda is lying on top of Archie and Otto surprises them, Archie screams and his hands are down by his waist. When it cuts his arms are suddenly waving above his head.

Continuity: When Archie dances with Wanda at the flat, they stop and you see Wanda put her hands around Archie's neck. The camera angle changes and her hands are now on his shoulders. The camera angle changes again and her hands are back around his neck. Happens about 3 times during the entire scene. There is even a time when only one hand is on his shoulder.

Continuity: When one of the robbers finds the box of diamonds that they are looking for, he is seen taking 1 envelope out of the box, pushing the box to the side, and opening the envelope on the table. The camera angle changes to a close up and he is seen opening the envelope on top of the box containing all the other envelopes.
