Know Any Movie Mistakes?

[Son of Enik]

One of my personal favorite movie mistakes happens in "Raiders of the Lost Ark". In a scene where Indy is in a plane, there is a superimposed image of a map as he sinks back into his seat. On the map we see a country marked Thailand...but because of the time period in which this movie takes place, the country should read Siam.
Another one that comes to mind is in "Abbot & Costello Meet Frankenstein", where they also meet Dracula and the Wolfman. Well, there is a scene in front of a large mirror and (Gasp!) we see Dracula's reflection! These are two movie blunders that stick out in my mind.

In "Who Framed Roger Rabbit?", some of the toons that appered after 1941 (when the movie takes place), one notable example is Tinkerbell, who appeared around the early 1950s(?)

There are many conflicting characters like that that appear in the movie. Some of the character's appearances aren't even directly form that era either. Someone posted somewhere a list of characters that appear in the movie, and which ones were historically inaccurate.
