Seamus Davey-Fitzpatrick (b. 29 December 1998, New York City) is an American actor. His first film role is as Damien Thorn, the Antichrist, in the 2006 remake of The Omen. He grew up in East Stroudsburg, Pennsylvania, where he currently lives. He attends J.M. Hill Elementary School, where he has most recently completed the first grade; his favorite school subjects are gym and recess. His parents are James H. Fitzpatrick, an actor and model, and Marty Davey, who is an actress. He began acting in commercials for Marriott and Flintstone Vitamins, and also briefly appeared in an episode of the television series Sex and the City. During filming of The Omen, Davey-Fitzpatrick was never told that his character was supposed to be the son of the Devil; co-star Julia Stiles has commented that it was because the filmmakers thought "he was too young to understand it". Seamus recently acted, along with his parents, in a local short film The Lottery, an eleven-minute adaptation of Shirley Jackson's short story. In March of 2007 he acted in a short film directed by Jonathan Budine.
