A successful child actor who managed to transition to a wide range of adult roles, Spencer Treat Clark is best known for his supporting parts in major Hollywood films released around the turn of the 21st century. The Northeast native had a number of television roles, including a stint on the soap "Another World" (NBC, 1964-1999), before his 10th birthday, and soon graduated to feature films, making his movie debut as the son of Jeff Bridges' character in the tense drama "Arlington Road" (1999). The following year, Clark had notable parts in the Oscar-conquering period film "Gladiator" and the enigmatic thriller "Unbreakable." Aside from an appearance in the lauded crime drama "Mystic River" (2003), he largely focused on his studies while in his teens, eventually resurfacing prominently in the horror remake "The Last House on the Left" (2009). Clark made a few TV guest appearances before firmly reestablishing himself as a screen presence in Joss Whedon's Shakespeare adaptation of "Much Ado About Nothing" (2012).
