Lady Luck is a 1936 American comedy film directed by Charles Lamont and starring Patricia Farr, William Bakewell and Duncan Renaldo.

In New York City, Mamie Murphy is working as a manicurist when she hears on the radio that she has won $2,500 on the racehorse Lady Luck in a sweepstakes draw, with the chance to win a further $150,000.

Conroy, who is actually a financially strapped playboy, is visited at his home by mild-mannered James Hemingway, who half-heartedly threatens him with a revolver and tells him to stay away from his wife.

The next day at the salon, Mamie signs a deal with theatrical agents Feinberg Goldberg Sternberg & O'Rooney that will give her a career in showbiz, but only if she wins the $150,000.

Conroy unexpectedly arrived ahead of the banker, realized a plot was going on, and threatened to notify the police so that Mamie's fortune and his marriage to her would not be jeopardized.
