Best comedy movie mistakes of 1991
Continuity mistake: During the wedding reception, George (Steve Martin) is called outside to meet with the police because there are too many cars parked in the street. Notice that the police car is curbside completely surrounded by cars. In fact, the whole street is packed with cars, making one wonder how the police car got up to the house.
Continuity mistake: At the conference, when the President is announced, there is a wide shot of the crowd and you see a lot of people standing in the background against the wall. There are also several spotlights turned on. Then it cuts to the stage where Frank and the squad are walking. When it cuts back to the crowd all the people in the background are gone and the spotlights are switched off. The crowd reappears later and the spotlights are on again.
Other mistake: Just before the evil robots capture Bill and Ted's girlfriends, after they crash through the window, the girlfriends ask the robots: "Who are you?" and Bill goes "Well, I'm really Evil Ted!" and unzips himself and out pops Evil Ted, and the other robot goes, "And I'm really Evil Bill!" and out pops Evil Bill. When the robots are herding the girlfriends out just before knocking them out with their breath, you can see two sets of clothes in the bottom left corner if you watch closely.
Continuity mistake: When the jumper shoots Kuffs before going off the ledge, pay attention to the trajectory of the bullet fired from the gun and then to the bullet wound that Kuffs shows us in the taxi cab. They don't match. If the bullet got him where it was supposed to, he would've been hit in the hip/upper thigh area, instead of the side of his abdomen like in the cab.
Continuity mistake: When Tommy and Darwin Mayflower are in the back of the limo, Darwin dives out and the door slams immediately before Tommy has time to catch it. The shot changes to outside the limo and Darwin is just now jumping from the limo. It is not just the same shot from a different angle because this time the door stays open much longer, long enough for the limo to drive out of the shot. From this angle there would have been more than enough time for Tommy to grab the door.
Continuity mistake: In the scene where Sue-Ellen has just come home from work, she places her pocketbook on the kitchen island. In the next scene the secretary is going through Sue-Ellen's office and finds her pocketbook and goes through it. How can that be if Sue-Ellen brought it home with her?
Continuity mistake: The scene is where Duncan is sitting across from Ralph trying to convince him that he's the king. It's a taco stand or something. At the start of the scene you see a bottle of Tabasco sauce on the table. In the next view, the bottle is gone and Ralph gets up to get a bottle of Tabasco sauce from the counter.
Continuity mistake: As the cops are taking the Hit and Run Son away, notice he his carrying a red plaid tote bag. Later in the movie, it miraculously appears in the possession of Still Working on the Same Painting. It can be plainly seen as she and her friend, Having a Day, are walking into the city sunset.
