Marcus Paul "Marc" Blucas (born January 11, 1972) is an American actor, known for playing Riley Finn in Buffy the Vampire Slayer and Matthew Donnally on Necessary Roughness.
Blucas was born in Butler, Pennsylvania. His mother, Mary Catherine (née Gordon), is an educator, and his father, Walter Joseph Blucas, is a school superintendent. They are divorced. After moving to Girard, Pennsylvania (a town near Erie), he became the star player on the Girard High School basketball team. He also played basketball at Wake Forest University, graduating in 1994 after one season playing on the same court as Tim Duncan. He was also a member of the Sigma Phi Epsilon fraternity.
After Blucas failed to make it into the NBA, he moved to England, where he played professional basketball for a year with British Basketball League's Manchester Giants. He later decided to become a lawyer, but changed his mind and went into acting instead.
Blucas's first television role was in the television movie Inflammable, made in 1995. From there, he found roles in both television and film. He starred as the Basketball Hero in Gary Ross's Pleasantville (1998). However, he finally landed his first major role in 1999, as Agent Riley Finn in Buffy the Vampire Slayer. Initially, Blucas was certain that he had blown his audition and had left apologizing for having wasted creator Joss Whedon's time. Whedon asked him to audition again, and he received the part two weeks later. He played Buffy's love interest until 2000.
His character in "Summer Catch" was based on real life Cape League baseball player Michael Macone.
After his departure from the series, he went on to star in such film as We Were Soldiers (2002) alongside Mel Gibson and Chris Klein and First Daughter (2004) with Katie Holmes. In 2007 Blucas began to land leading roles in films such as Thr3e and The Killing Floor.
In February 2010, Blucas joined the cast of the ABC television drama pilot True Blue.
Blucas was part of the regular cast of the USA Network show Necessary Roughness for the first two seasons, playing Matthew Donnelly. The series premiered on June 29, 2011.
On July 25, 2009, Blucas married journalist Ryan Haddon, daughter of Dayle Haddon and is stepfather to her children from her first marriage to actor Christian Slater.
