Mercedes McNab Career

Mercedes McNab began acting professionally when she was 10 years old. Her career spanned two decades, from 1991 to 2011, and covered feature films, television series, direct-to-DVD productions, and magazine editorial work.

The Addams Family Years (1991-1993)

McNab’s first screen role came in the 1991 Paramount feature The Addams Family, directed by Barry Sonnenfeld.

She played a Girl Scout selling cookies in a brief but memorable scene opposite the film’s main cast, which included Anjelica Huston, Raul Julia, and Christopher Lloyd.

That small appearance led directly to a larger opportunity. In the 1993 sequel Addams Family Values, she returned in the expanded role of Amanda Buckman, a snobbish, self-important camper at Camp Chippewa.

Her comedic performance opposite Christina Ricci’s Wednesday Addams earned wide notice among fans of the franchise.

Between the two Addams Family films, McNab also picked up early television credits.

She appeared in Harry and the Hendersons in 1991, Touched by an Angel in 1994, and Walker, Texas Ranger in 1993.

Buffy the Vampire Slayer (1997-2004)

McNab’s most defining role came in 1997 when she auditioned for the lead role of Buffy Summers on Buffy the Vampire Slayer for The WB network.

That role went to Sarah Michelle Gellar. Instead, the producers cast McNab as Harmony Kendall, a vapid and popular high-school student in Sunnydale.

Harmony became a vampire during the season three finale and returned across multiple seasons.

McNab appeared in 16 episodes of Buffy over four seasons, from 1997 to 2001. The character balanced comedy with moments of genuine menace, and McNab’s timing drew consistent praise from the show’s creator Joss Whedon and its fanbase.

The role carried over into the spinoff series Angel, which starred David Boreanaz as the vampire-with-a-soul.

McNab first appeared in Angel in a guest spot in 2001, then returned as a series regular for the show’s fifth and final season, which aired from 2003 to 2004.

She played Harmony across 17 episodes of that spinoff.

Her tenure on both shows totaled more than six years of work within the Buffyverse. The cancellation of Angel in 2004 ended that chapter of her career.

Horror Films and Later Work (2005-2011)

After Buffy’s universe wrapped, McNab continued working across television and genre films.

She guest starred on Supernatural, Psych, Reaper, Criminal Minds, Crossing Jordan, Boston Public, and Dawson’s Creek.

Her next major screen credit came with the slasher film Hatchet, released in 2007 and directed by Adam Green. McNab played Misty, one of the lead characters in the bayou-set horror film.

The project positioned her as a fixture in modern horror cinema and drew favorable comparisons to classic Scream Queens.

She briefly reprised the role in Hatchet II in 2010. Between those films, McNab appeared in a series of direct-to-DVD horror projects, including Dark Reel (2008), Thirst, and XII.

She also appeared in the television film Vipers alongside actress Tara Reid and in Medium Raw: Night of the Wolf.

Away from scripted work, McNab served as the cover model for the November 2006 issue of Playboy magazine and also appeared in the January 2004 issue of FHM.

Her final acting credit came in 2011 with the comedy Glass Heels, after which she stepped away from professional acting permanently.
