Born in Oklahoma City in 1942, Pamela Tiffin Wonso grew up in Chicago, where she began a modeling career while in her early teens. She moved to New York to model and attend college, but became so successful in her modeling career that college soon took a back seat. On a trip to California she met producer
Hal B. Wallis (husband of actress
Martha Hyer) who was so impressed with the beautiful teenager that he cast her in the
Tennessee Williams drama
Summer and Smoke (1961). Her sterling performance netted her nominations for two Golden Globe awards (in the Best Supporting Actress and Most Promising Female Newcomer categories) in early 1962. Later that year she married American journalist, editor, and magazine publisher,
Clay Felker.
She posed for a number of cheesecake shots in the 1960s and appeared in several lighthearted, frothy romantic comedies. Legendary director
Billy Wilder was taken with her comedic skills and cast her in the Coca-Cola-themed
One, Two, Three (1961) (with
James Cagney and
Arlene Francis), and she appeared in such comedies as
The Pleasure Seekers (1964) (with
Ann-Margret and
Carol Lynley) and
For Those Who Think Young (1964) (with
James Darren and
Tina Louise) and
Harper (1966) (starring
Paul Newman).
By the mid-1960s, with her marriage ending, she went to Italy to star in some comedies including
Straziami ma di baci saziami (1968) (with
Nino Manfredi and
Ugo Tognazzi), directed by
Dino Risi. In these comedies she showed an excellent adaptability to act as a small-town Italian girl. In 1974, she remarried and retired from the screen to raise a family and pursue other interests. She lived in New York with husband Edmondo Danon and her two daughters until her death in 2020, aged 78.
