According to Suzanne Finstad's 2005 biography of
Warren Beatty, Dunn
(spelled Dunne in the book), was a casting director at CBS in 1957 and
gave Beatty his first acting role in a 15-minute Sunday religious show,
Lamp Unto My Feet. Another CBS employee, Pamela Illott, is quoted by
Finstad as saying that Dunn discovered
Steve McQueen for the same
program, and also
George C. Scott.
