Revealing mistake: At the end, when all the historical figures are going back into the phone booth, you can see the trap door in the back open and the people go through it. It would be kind of tight to fit all of them in the booth at the same time.

Bill & Ted's Excellent Adventure (1989)
1 revealing mistake - chronological order
Directed by: Stephen Herek
Starring: Keanu Reeves, George Carlin, Alex Winter
Continuity mistake: At one point, when they time-travel away from "1,000,000 B.C.", Bill is on the left inside the phone booth and Ted is on the right. When the camera switches away, then back, they've changed sides.
Abraham Lincoln: Fourscore and...[looks at his pocket watch]...seven minutes ago... We, your forefathers, were brought forth upon a most excellent adventure conceived by our new friends, Bill...and Ted. These two great gentlemen are dedicated to a proposition which was true in my time, just as it's true today. Be excellent to each other. And... Party on, dudes!
Trivia: Jane Wiedlin, who plays the role of Joan of Arc, was the guitar player of the rock band The Go-Go's.
Question: Why was Beethoven arrested? He wasn't doing anything illegal.





Answer: While it's not unusual for musicians to try out new instruments (playing a few rifts and even entire compositions) in a music shop, Beethoven's extended sampling-keyboard performance went wild, drawing an enthusiastic mall crowd into the relatively small music shop. The shop manager no doubt felt overwhelmed and called in mall security to clear out the shop before any damage and/or theft occurred. Keep in mind that the security team was already scrambling to respond to several simultaneous disturbances throughout the mall, all caused by 7 strangely-dressed oddballs (more than half of whom only spoke obsolete dialects and ancient languages). The time-travelers were, thus, probably all perceived as one group of pranksters or escapees from a mental institution.
