Anachronisms: In the first scene of the film, Fuller writes the letter with a fountain pen. This is clear in the close-up where the "feed" is visible under the nib. It also has a cap. The pen is dipped into a desk inkwell. Fountain pens are never dipped into an inkwell. It is set down in a grove on the desk set, which would be a correct action for a dip pen, which it was not.
