Alexis Denisof (born February 25, 1966) is an American actor, primarily known for playing Wesley Wyndam-Pryce in the television series Buffy the Vampire Slayer and its spin-off Angel.

After graduating from St Paul's School in Concord, New Hampshire at the age of 17, he moved to London, England, where he lived and worked for several years.

[7] His first lead role was alongside Sir Christopher Lee in the feature film Murder Story (1989) where he played an investigative reporter.

Originally, Wyndam-Pryce was supposed to be killed off in the season 3 finale but, due to Whedon's surprise at how well he fit into the series, Denisof was given the choice about his character's fate and chose for him to live.

Save for appearing in three episodes of the hit series How I Met Your Mother, as the goofy philandering Sandy Rivers, Denisof would not work as much as he used to for the next several years.

In a season 1 commentary, creators Craig Thomas and Carter Bays speculated that Denisof was initially reluctant to take the role back in 2006 because he feared it was just charity work on account of his wife, Hannigan, playing a main character on the show.

The second was the lead male role in a modern version of Shakespeare's Much Ado About Nothing, which premiered at the Toronto Film Festival, to positive reviews from critics.

[15] On November 28, 2018, Deadline Hollywood reported that Denisof would play the recurring role of Adam Masters in the second season of Netflix's Chilling Adventures of Sabrina.

[8] Denisof married past co-star Alyson Hannigan, who played Willow Rosenberg in Buffy the Vampire Slayer, on October 11, 2003.
