He is also known for the film Another Earth.
Early life and education
Mapother was born in Louisville, Kentucky, the son of Louisa () and William Reibert Mapother Sr. His father was an attorney and served as a judge in Louisville between 1967 and 1970. Mapother Jr. is a first cousin of actor Tom Cruise, whose birth name is Thomas Cruise Mapother IV.
Career
Mapother has become widely known as a character actor, and sometimes plays scary or otherwise dark characters. He played a pivotal role in Todd Field's In the Bedroom, and is perhaps best known as Ethan Rom in the TV show Lost, which he played for 11 episodes during the life of the series.
Mapother has also had considerable roles in a series of independent films, such as The Lather Effect, Moola, Hurt, and Another Earth. Mapother starred in The Burrowers as a Native American fighter who joins a posse to help find missing white settlers.
In September 2007, he was elected to a three-year term on the National Board of Directors for the Screen Actors Guild.
He has provided the motion capture work for Agent 47, the main character in the 2012 video game Hitman: Absolution and also provided the voice before series veteran David Bateson was recast. In 2014, he played the lead in the paranormal horror film The Atticus Institute.
Awards
William Mapother received a nomination for a Gotham Award for the film In the Bedroom in 2001, but a search for a specific ACCA nomination in 2001 or an Actor Award for Outstanding Performance by the Cast of a Theatrical Motion Picture in 2002 for him did not yield results, though he did not win the Gotham Award.
