Robin Hood: Prince of Thieves: Telescope Didn’t Exist Yet
There is a specific scene in the movie where Morgan Freeman and Kevin Costner’s characters used a telescope. This should have been impossible because the device was only invented during the 1600s. The tale of Robin Hood is set during the 12th century so its introduction was a couple of centuries too early.
Catch Me If You Can: Braces Didn’t Exist Yet
This movie features a star-studded cast, an exciting plot, and the direction of Steven Spielberg. Despite all of these, the tale of Frank Abagnale Jr. was not told without errors. Case in point: Amy Adams’ character was sporting braces, despite the movie taking place in 1963. The orthodontic devices would only be introduced in the 1970’s.
