His Prehistoric Past is a 1914 American short silent comedy film, written and directed by Charlie Chaplin, featuring Chaplin in a stone-age kingdom trying to usurp the crown of King Low-Brow to win the affections of the king's favorite wife.

Back in the Stone Age, King Low-Brow, King of Wakiki Beach, sits surrounded by his six favorite wives as they watch a man dancing to entertain them.

Charlie arrives in this land wearing a black hat, caveman-style.

He meets and falls in love with the King's favorite wife.

Charlie throws a rock at the hunter but misses and hits the king on the head.

They go hunting with a bow and arrow, and Charlie fires at a bird in a nest above, breaking an egg which lands on the king's head.

A reviewer from the San Francisco Call and Post wrote, "Charles Chaplin and other members of the Keystone Company have outdone all their previous fun-provoking efforts in the two-part film called His Prehistoric Past, which puts Chaplin in a dream state during which time he goes through a series of prehistoric difficulties, trying enough to discourage even the strongest 'stone age' man.
