  • In the beginning when Bill and Ted are leaving class, the writing on the blackboard clearly says "Ghenghis Khan". A few seconds later it says "Genghis Khan".
  • When the historical dudes are filing into the phone booth at the end of the movie, a trapdoor in the back is visible as they go through it.
  • There is a heinous number of most egregious anachronistic errors in the depiction of the famous historical dudes, their lives, their works, their time periods and the state of their hearing.
  • At the end, a podium appears and disappears between shots.
  • People endlessly swap places in the ever-expanding phone booth. Sometimes they disappear altogether.
  • After the "gum and cans" repair to the booth's antenna, some later shots of the booth show an undamaged antenna. It's most noticeable in the "Circuits of History" and the presentation at the end of the film.
  • As Bill and Ted are about to journey off from Ted's house for the first time, his dad's police car jumps between the driveway and sidewalk several times.
  • In the Steadicam shot inside the jail, as the camera leads to Freud, the boom mic drops in and out of the shot just before the angle changes.
  • When the phone booth lands at the Circle K for the first time, the antenna on top of the phone booth falls off. It re-appears in the next scene.
  • In the saloon fight when Billy the Kid is caught cheating at cards, a prostitute swings in on a rope and takes a guy through a window with her. The rope she swings on disappears and re-appears a few times between shots.
  • When Rufus leaves in the phone booth (at Ted's house) and the empty booth drops down, Bill and Ted are right next to each other in close shots, but are 3 or 4 feet apart in the medium/long shots.
  • When the phone booth is first created, one shot shows Rufus' face with a complete booth reflected. In the next shot, the booth is still forming.
  • When Bill and Ted pick up Genghis Khan in Outer Mongolia, the screen card says it's 1209. During the report, Bill says they picked him up in 1269. Genghis Khan died in 1227. In 1269, the Mongol Empire was ruled by Kublai Khan, Genghis' grandson.
  • When Bill and Ted arrive in New Mexico, the phone booth lands in front of a Saguaro cactus, which does not grow naturally in New Mexico.
  • When Bill and Ted land in the future, they tell Billy the Kid and Socrates to stay put. Socrates nods in understanding. In Greece, nodding means no and shaking one's head means yes.
  • During the water slide sequence, Napoleon appears to be wearing modern underwear underneath his historical undergarments. He could have acquired them during his time in 1988 San Dimas.
  • During their report, Bill and Ted say that Joan of Arc drove the English out of France and had the Dauphin crowned by the time she was 17. Joan was 17 when she began her career and had the Dauphin crowned. The English were driven out in 1453, the year France won The Hundred Years' War.
  • When the phone booth is formed, the reflection of it in Rufus' glasses is clearly a photo; the text at the top is not reversed.
  • When Abraham Lincoln gets in to the booth for the first time, his hat falls off outside. He still has his hat in later scenes.
  • Napoleon looks at and tries ice cream as if he's never seen it before. In reality, Catherine de Medici introduced the French to ice cream when she married the future King Henri II over 250 years before Napoleon's reign. Napoléon Bonaparte more than likely had ice cream before his time travel to San Dimas.
  • When Bill and Ted tell Socrates in his original time, 410 B.C., that they're dust in the wind, Socrates says, "Yes! Like the sands of the hourglass!" The hourglass was first introduced to Europe in the 8th century AD. (It's an in-joke about Days of Our Lives (1965).)
  • There were no humans, or reasonably similar creatures, in California in 1,000,000 B.C.
  • Bill and Ted introduce Rufus to themselves, but Rufus never told them his name.
  • When Napoleon is stuck in the tree, he disappears when the camera angle changes to an aerial view of Bill and Ted.
  • 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.
  • When Bill and Ted get Beethoven in 1810, he's playing a Steinway piano, invented in 1853.
  • When Bill reads the assignment to Ted, he says, "Express to the class how an important historical figure from each of your time periods would view the world of San Dimas, 1988." His lips actually say, "San Dimas, 1987". The "1988" was dubbed later because of a delay in the movie's release.
  • When Bill and Ted first see the castle that contains the princesses, it has a lightning rod. Lightning rods were invented in 1749 by Benjamin Franklin.
  • Beethoven is picked up by the dudes in 1810. By that year, the real Ludwig van Beethoven was almost completely deaf. Yet Beethoven responds to characters' spoken words, musical notes, and other aural cues at several points during the film.
  • When the dudes pick up Socrates in 410 BCE, the buildings of Athens are stark white ruins. At the time, they were active buildings, painted in bright colors.
  • The 15th-century castle commandant orders that the spies be executed in the Iron Maiden, which Bill and Ted take to mean Iron Maiden. This "medieval instrument of torture" was invented in 1793 for display in museums.
  • In the music credits, Glen Burtnick's last name is misspelled as "Burtnick."
  • When future Bill and Ted are at The Circle K with Rufus, Ted reminds his past self much sooner than the conversation seen later.


  • When Socrates pushes a medieval knight off the horse-drawn wagon during the escape to the phone booth, it's quite obviously a stunt double, most notably by the man's face.
  • At the beginning of the presentation, Billy the Kid shoots out a light with his gun. He had just been broken out of jail, where the police would have undoubtedly taken his gun. The presentation includes a couch for Freud, swords for Joan of Arc, keyboards for Beethoven, a halberd for Genghis Khan, and battle maps/pieces for Napoleon. Future Bill and Ted likely got Billy a gun for the presentation when they came back to set everything up.
  • After finishing their History Presentation and returning all the Historical Figures to their own time periods, Bill and Ted are back in the garage filming a rock video, and the Time Machine is standing outside the garage door. Minutes later, there is a flash and Rufus arrives with the Princesses in his own Time Machine. When the garage door opens, only one Phone Booth is outside, not two.
  • When Bill and Ted are at the Circle K, and the phone booth with their future selves lands, Bill says "Aw, I hate that part" just as they land in the booth. When they land at the Circle K to talk to their past selves at the end, Bill doesn't say that.
