Hagan Beggs was born on March 19, 1937 in Belfast, Northern Ireland, UK. He was an actor and set decorator, known for Titanic (1996), The Changeling (1980) and Star Trek (1966). He was married to Anna Hagan. He died on September 16, 2016 in Vancouver, British Columbia, Canada.
He and his wife changed their stage names, as there were already actors with the same birth names. Margaret (Maggie) Smith became Anna Hagan, (her grandmother's maiden name), and James Beggs became Hagan Beggs, an homage to his wife.
