Appeared in many TV, radio and stage productions of the works of Samuel Beckett.
Attended St. Patrick's Roman Catholic College in County Armagh, Northern Ireland.
He and his wife Belle (who, like Magee, was also from Armagh, Northern Island), had twins in London in February 1961. Their son was named Mark and their daughter Caroline.
Magee had a reputation as a heavy drinker, which may have caused his premature death from a heart attack at 60.
When beginning his stage career, Patrick McGee chose to alter his surname to Magee. It's unclear why he chose to do this, although there have been reports that there was another actor named Patrick McGee, and that Magee wanted to avoid confusion.
Won Broadway's 1966 Tony Award as Best Supporting or Featured Actor (Dramatic) for playing the Marquis de Sade in Peter Weiss' "Marat/Sade," a performance recreated in the film version of the same title, Marat/Sade (1967).
