He spent much of his adolescence living in the Old Rectory, Kinnitty, Birr, County Offaly, where his father, Reverend Francis Hitchcock, was the Church of Ireland rector.

Mathis and Ingram would go on to make four films together: Hearts Are Trumps, The Four Horsemen of the Apocalypse, The Conquering Power, and Turn to the Right.

They formed a small studio in Nice and made several films on location in North Africa, Spain, and Italy, for MGM and others.

[6] Among those who worked for Ingram at MGM on the Riviera during this period was the young Michael Powell, who later directed (with Emeric Pressburger) The Red Shoes and other classics, and technician Leonti Planskoy.

MGM studio chief Dore Schary listed the top creative people in Hollywood as D. W. Griffith, Ingram, Cecil B. DeMille and Erich von Stroheim (in declining order of importance).

The film was not a commercial success; he then left the movie business, returning to Los Angeles to work as a sculptor and writer.

Frequently pedestrian and pretentious, Ingram's films nevertheless contain splendid flashes of macabre fantasy, such as the ride of the Four Horsemen in the Valentino epic, or the 'ghoul visions' that bring about the death of the miser in The Conquering Power.
