Attended Orange Coast College in Costa Mesa, California.
The son of actors Bill Williams and Barbara Hale, curly-haired leading man William Katt is fond of noting that he made his movie "debut" while residing in his mother's womb during filming of Lorna Doone (1951). After attending Orange Coast College, Katt pursued a career as a musician. He then made his formal acting bow in summer stock and small TV roles. Among Katt's film credits are the role of the high-school jock date of telekinetic wallflower Sissy Spacek in Carrie (1977), and one-half of the title role in Butch and Sundance, The Early Days (1979). From 1981 through 1983, Katt played the reluctant-superhero protagonist (originally named Ralph Hinkley, redubbed Ralph Hanley after the '81 assassination attempt on Ronald Reagan) on TV's Greatest American Hero. Beginning in 1987, Katt played the recurring role of detective Paul Drake Jr. in the periodic Perry Mason TV movies, co-starring with his mother Barbara Hale, who resumed her "Della Street" characterization from the original 1961-66 Mason run. Katt also worked on the scripts of several of these latter-day Masons. More recently, William Katt was a regular on the 1991 Farrah Fawcett-Ryan O'Neal TV sitcom Good Sports. ~ Hal Erickson, All Movie Guide
