Roma Downey was born on May 6th of 1960 in Derry, Northern Ireland. Raised in a Roman Catholic household in the district of Bogside, Roma attended Catholic schools as a child and was raised primarily by her father, as her mother passed away from a heart attack when she was 10. Although she initially gravitated towards painting and earned a Bachelor of Arts at Brighton College of Art, she later became interested in drama while in university.

Roma Downey began her career in theatre and toured the United States with a stage production of "The Playboy of the Western World." She then got an agent in New York City before booking roles in Broadway productions like "The Circle." In 1991, she appeared as Jackie Kennedy in the miniseries "A Woman Named Jackie," which led to another central role in "Touched by an Angel." Downey appeared in the series for the next nine seasons before the show ended in 2003.

In 2011, she and her husband Mark Burnett began work on "The Bible," a ten-hour docudrama that aired on the History Channel. The show eventually aired in 2013 with Roma playing the role of Mary, mother of Jesus. The series was well-received and led to a number of spin-offs and sequels, including "Son of God" and "A.D." The couple then produced another miniseries called "The Dovekeepers."

Roma Downey has appeared in films like "Borrowed Hearts," "Second Honeymoon," "Monday After the Miracle," "Come Dance at My Wedding," "Keeping Up With the Randalls," and many other projects. In 2014, MGM purchased a controlling interest in One Three Media and Lightworkers Media – the latter of which Roma founded with her husband. In 2015, MGM then purchased 45% of Downey and Burnett's stake in United Artists Media Group.
