The Big Wheel is a 1949 American drama sport film directed by Edward Ludwig starring Mickey Rooney, Thomas Mitchell, Mary Hatcher and Michael O'Shea. It includes the final screen appearance of Hattie McDaniel. This film is now in the public domain. Plot Billy Coy (Mickey Rooney) arrives in the town of Carrell, California and offers himself as a mechanic for Arthur "Red" Stanley (Thomas Mitchell) at his garage. Red turns down Billy initially, but after seeing a photo of his father, "Cannonball" Coy, a famous driver, Red scares up a job for Billy. Billy's father died in an accident at the Indianapolis 500 several years previously. Red was Cannonball's mechanic, riding with him the day he died in the north turn of the Indianapolis motor speedway. Red inquires after "her"; he still carries a torch for Mary (Spring Byington), Cannonball's widow and Billy's mother. At the garage, Billy befriends a tomboy, Louise Riley (Mary Hatcher), whose father owns the nearest racetrack. Billy gets a chance to prove his skills as a driver in a qualifying race, but he is too arrogant to follow his employer's advice and is unsuccessful. He asks Louise to meet on Saturday night at the track. Thinking it is a date, Louise does the unheard of for her—she buys a dress and heels (in which she is unskilled at walking), assisted by her family's maid (Hattie McDaniel). As it turns out, Billy needed her help with changing some carburetors, much to Louise's disappointment. She gamely wobbles on high heels with him to the garage, buoyed by her love of cars and affection for Billy. Billy gets another chance to drive for another car owner, Deacon Jones. The car is green and referred to as a "Hoodoo Wagon" due to a racing superstition that green cars are unlucky. A helpful gadfly in the pits reminds Billy this is the same color as the car his father drove when he crashed and burned. Billy drives but is pushed off the track by driver Vic Sullivan (Michael O'Shea). Billy survives the crash but fails to qualify. He vents his frustration at the dirty trick by punching Vic. Distracted by the spectacle, another driver injures his hand by absentmindedly placing it on the searing exhaust pipe of his car in which he's sitting; Billy is offered the opportunity to drive in the incapacitated man's stead. Billy wins the next race
