When the Clouds Roll By is a 1919 American comedy film starring Douglas Fairbanks and directed by Victor Fleming and Theodore Reed.

In the midst of a series of bewildering misfortunes apparently emanating from broken mirrors, black cats, and similar sources, Daniel meets Greenwich Village artist Lucette Bancroft (Kathleen Clifford), and mutual love results.

A Westerner who owns land in partnership with Lucette's father comes to the city and plots with Daniel's uncle Curtis (Ralph Lewis) to defraud his partner.

"Executed at a breathless pace, When the Clouds Roll By is a masterful showpiece for the whirling cyclone of energy that was Douglas Fairbanks."

Vance also notes that the film's flood sequence conclusion presages a similar ending in Buster Keaton's classic Steamboat Bill, Jr.
