Alyson Hannigan Biography


Born Allison Lee Hannigan in Washington, D.C. to an Irish-American father and a Jewish-American mother, her first film role was in My Stepmother Is an Alien (1988). Before that she had done a little television work, mostly commercials, and she went on to do a good deal more including Almost Home, Picket Fences, Roseanne and Touched by an Angel before being chosen for Buffy in 1997. By the final season she was earning $250,000 an episode.

It was announced in October 2003 that she had signed a deal with NBC to appear in a comedy, expected to debut in fall 2004. Reports indicated that it was likely to be titled Americana, but the pilot was not part of NBC's 2004 fall lineup.

In early 2004, Alyson Hannigan made her West End debut starring in a stage adaptation of When Harry Met Sally... at the Theatre Royal Haymarket, opposite Luke Perry.

Alyson Hannigan owns a home in Sacramento, California and married actor Alexis Denisof (who played Wesley Wyndam-Pryce in the Buffy franchise) on October 11, 2003. Previous relationships include actor Steven Sutphen and Marilyn Manson drummer Ginger Fish.

In 2005, Alyson Hannigan is one of several Buffy cast returning to television, others being David Boreanaz, Nicholas Brendon, Charisma Carpenter and James Marsters. She is a series regular on How I Met Your Mother, and also has a recurring guest role on Veronica Mars.

Alyson Hannigan's somewhat unstereotypical beauty and distinctive acting style have led her, for the most part, to choose somewhat quirky characters. Her best known roles in Buffy the Vampire Slayer and the American Pie series are clear examples of this.
