Margaret Whitton billed herself as Peggy Whitton when she made her off-Broadway debut in 1973's Baba Goya. Whitton made her first Broadway appearance nine years later in Steaming. In films, she has been effectively cast as what is vulgarly known as the "rich bitch" — never more effectively than as avaricious baseball-team owner (and former exotic dancer) Rachel Phelps in the two Major League pictures. Margaret Whitton's TV-series work includes the 1991 soap-opera spoof Good and Evil, in which the producers cunningly pulled a typecasting reversal, hiring Whitton as "good" Genny and Teri Garr as "evil" Denise.
