Alexis Denisof (born February 25, 1966) is an American actor of Russian descent, who is best known for playing Wesley Wyndam-Pryce in the television series Buffy the Vampire Slayer and its spin-off Angel. Wesley's character was first introduced in Buffy the Vampire Slayer season 3 as Buffy Summers' replacement Watcher. After Buffy parted ways with the Watchers' Council, Wesley was out of a job. He later showed up on Angel, and became a regular character in that series from episode 11.
Although Denisof is an American, born in Salisbury, Maryland, he lived and worked in Britain for a number of years. Whilst living there he dated the comedienne Caroline Aherne (he is given a special thanks in the credits for The Royle Family) and appeared with Sean Bean in three Sharpe stories. He has done many stage productions, including one with Anthony Stewart Head, who played Wesley's predecessor Rupert Giles on Buffy.
In 2006, Denisof has had a recurring role as Sandy Rivers on his wife Alyson Hannigan's show How I Met Your Mother.
Denisof was an early contender to portray James Bond in the upcoming 2006 movie Casino Royale; however, the role was eventually awarded to Daniel Craig.
Denisof married Alyson Hannigan, who played Willow Rosenberg in Buffy the Vampire Slayer, on October 11, 2003. They live in Los Angeles, but also have a home in London.
