Which Way Is Up? (1977)

"Three times the Richard Pryor. Three times the laughs."

Orange picker Leroy Jones inadvertently becomes a union leader and is forced out of town, leaving behind his sex-obsessed father, Rufus, and timid spouse, Annie Mae. He heads for Los Angeles, where he falls for union organizer Vanetta. Annie Mae seeks solace from local preacher Lenox Thomas, who eventually impregnates her. When Leroy catches wind, he heads home for a showdown with Lenox.
