Charlie Chaplin and his brother Sydney were two of the most well-known names of the silent era, both hailed as comic geniuses.
In A Dog, a short comedic movie made in 1915 and directed by Chaplin himself, we see the brothers using their incredible physical and creative talents to great effect.
The scene is simple and fairly lighthearted: Chaplin is harassing Sydney who is trying to take a nap on a park bench.
He interrupts him again and again with gags, sketches, jokes - all perfectly performed with typical Chaplin brilliance - creating one of the most memorable moments from an early period in film history.
Both brothers come across as genuinely funny yet with enough heartwarming rapport between them that it transcends any performance or plot contrivance.
It's this unique combination of humour and emotion that made Charlie Chaplin into one of cinema's greatest legends.
