Early life and education MacGinnis was born in the Ranelagh area of Dublin in 1913, the son of Mary Josephine (née Kelly) and Patrick F. MacGinnis. He served through the end of Second World War, until 1947, when he returned to acting in the film Captain Boycott.
In 1953, MacGinnis played the title character in the biographical film Martin Luther. The film was critically acclaimed and a large commercial success, earning multiple Academy Award nominations and appearing on the National Board of Review's Top Ten Films of 1953. One critic called MacGinnis' performance "magnificent... given reverential, straightforward, honest, sincere treatment, as well as eschewing anything savoring of sensationalism."
In 1957, MacGinnis played the villain Dr. Julian Karswell opposite American actor Dana Andrews in the classic British horror film Night of the Demon (initially released in the United States as Curse of the Demon). His role as a sinister-yet-charismatic occultist remains one of his most well-remembered among film fans. Another notable role was as Zeus in the 1963 fantasy film Jason and the Argonauts.
Television On television, he played the arch-criminal A. J. Kent in the Danger Man episode "Battle of The Cameras" and Colonel Probst in The Saint episode "The Paper Chase".
Personal life During the late 1930s, MacGinnis lived on the River Thames on a houseboat converted out of a commercial sailer, the Hermoine.
In 1942, MacGinnis married Sheila Mcdonald; the couple later divorced. In 1955, he married his second wife Eleanor, with whom he had a daughter. In the mid-1970s, he gave up acting, moved back to his native Ireland, and returned to the medical profession. He lived in Ashford, County Wicklow.
Death MacGinnis died of cancer in Haverfordwest, Pembrokeshire, Wales, in January 1977, aged 63, where he had been working in a local clinic. At the time of his death, he was considering coming out of retirement to appear to narrate his old friend Michael Powell's film Return to the Edge of the World (1978).
His wife Eleanor remained in Ashford until her death in 2013. Their daughter and family still reside on the family property.
