Liam Pádraic Aiken was born January 7, 1990 in New York City, to Moya and Bill Aiken, an MTV producer. His mother was born in Ireland, while his father was an American of Irish descent. It was apparent from the beginning that Liam was a natural actor. After securing a small part on Broadway in the award-winning production of Henrik Ibsen's "A Doll's House," Liam's big break came in 1997, when he played Ned in the movie Henry Fool (1997). From there he has created a snowball of films that has yet to stop rolling through Hollywood. With his eyes and facial moves, he has been compared to Jim Carrey, but when it comes to character portrayals, Liam is his own person, with his own unique style. When on the set, he had a tutor who gave him homework.[1]
While out promoting the 2004 movie his house burned down.
Was the first choice to play Harry Potter due to his Irish background experience with Chris Columbus.
This was considered by author J.K. Rowling at first, but later reiterated that the part should be played by a British actor, as she created a strictly British and Irish cast policy for all Harry Potter films. Aiken was then replaced by Daniel Radcliffe.
