Gallopin' Gals

Gallopin' Gals is a 1940 American one-reel Technicolor animated film directed by William Hanna and Joseph Barbera and produced by Fred Quimby. It belonged to the screwball comedy genre.

Plot
The film is a typical animated screwball comedy made in the style of such films as The Women (1939), except for the fact that the characters are fillies at the Kentucky Derby with New York accents, gossiping about some of the other contestants.

The underdog of the story is a shy, lonely horse named Maggie who has never won a race in her life and suffers from hay fever. During the race, the other horses competing are distracted by a photo finish. They fall short of the finish line, in second place simultaneously, while the picture is taken. Maggie crosses in front of them, winning the race.
