The Amazing Impostor is a 1919 American silent comedy film starring Mary Miles Minter and directed by Lloyd Ingraham.

[1] As described in various film magazine reviews,[2][3][4] Joan Hope (Minter) is the daughter of the "Chewing Gum King" (Periolat), who longs for adventure and romance.

Joan agrees eagerly, unaware that the "Countess" is in fact a crook in possession of stolen diamonds, who proposes the swap in the hope of avoiding the detective on her trail.

Quite unaware of this, Joan checks into a hotel under the name of the "Countess of Crex," trailed by Detective Kent Standish (Forrest), who is convinced that she is the real thief.

At this point Joan's father, having returned home to find his daughter gone, arrives at the hotel, along with the original fake Countess, who is seeking to exchange the box of chewing gum for the diamonds.
