High Speed Lee (1923)

James "Jimmy" Jefferson Lee, a wealthy, idle, adventure-loving young Long Islander, practices jumping his horse, an endeavor that cost his father his life. Jimmy begins a beautiful friendship with Jane when he accepts her dare to dive with her from the seventy-feet-high roof of the Yacht Club into the sparkling sound below. Displeased with Jimmy's shiftless ways, however, Jane prods him into devoting some time to his business interests, especially the All-American Tire Co., of which his rival, stodgy Harold Polk, is general manager. Jimmy's unconventional methods result in resignations by all the company's executives, but he manfully steers the business to financial success and, meanwhile, rides a dangerous horse called "Homicide"--thereby silencing those who scoffed at him and winning Jane's heart.
