Bill & Ted pick up Genghis Khan in the year 1209, and in the report, they say that they picked him up in 1269. Not only that, but Genghis Khan was dead by 1269. Ooops!

In the scene where they are getting Billy the Kid and Ted is picked up and thrown across the bar table, a close look shows that it isn't Keanu Reeves
but his stunt double Matt.

Look closely at the chase scene set in England between King Henry's guards and the horse cart that Bill and Ted are on. Just after the cart rides underneath the big arch, material falls off the top in an attempt to halt the chasing guards. But look even closer and you'll see that there is a rope connected to the back of the phone booth connected to a bundle of logs on top of the arch that helps to bring it down. If you were being chased by guards would you have time to tie a bundle of logs off a rope from an arch in a split second?
When the phone booth is being created, a reflection of the complete booth is visible in Rufus's sunglasses; the next shot shows the booth still being created.
