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: In the scene where Death and Bill are playing Twister, Bill's left hand was on red and his right hand was on green. In the next shot when Death is putting his foot on blue, Bills hands are switched. In the same scene Bill's shoes are on the floor. After he wins they walk over to Death and his shoes are back on. He never had time between all the dialog to put them on.

Continuity mistake: When Bill, Ted and Death are at the gates of heaven, they are all looking up to the gatekeeper, talking to him. Bill and Ted are in the foreground, with Death behind them. However, when we see a shot of them from behind, Death is in front of Bill and Ted.
Continuity mistake: If you watch the concert scenes, the audiences are all different because it was partially taped at Six Flags Magic Mountain and Culver City Studios. Hollywood (From G.L.O.W. Ladies Wrestling circa 1980's) was sitting in the front row on the viewer's right at the S.F.M.M. taping, and she's not there at the C.C.S. taping.

Continuity mistake: Near the end, when Ted catches evil robot Bill's head, the position of Bill's head changes in the next shot.
Continuity mistake: After getting the fake phone call from Joanna (evil Bill using her voice), Bill and Ted are sitting on the couch in their apartment. There's a knock on the door and Bill puts his hat on sideways. But when he opens the door, his hat is on backwards without adjusting it while walking to the door.

Continuity mistake: When Bill, Ted and their girlfriends are sitting at a table talking, Ted says "You probably noticed we haven't given you our gifts yet" with Pepsi cans visible on the table.

Chosen answer: Kimberley Kates (who played Elizabeth in the first film) said in an interview on a B&T fan podcast that she and Diane Franklin were scheduled to reprise the roles, but then heard that they had been recast. She believed it was because the English director Peter Hewitt did not like English characters being played by American actresses.
