The Role You Likely Forgot Alyson Hannigan Played On That '70s Show

Alyson Hannigan has been part of at least two iconic and long-running television series throughout her career. Many fans might remember her from "Buffy the Vampire Slayer" as Willow Rosenberg, the best friend of Buffy Summers (Sarah Michelle Gellar) and fellow California-based witch. Hannigan portrayed Willow for the entirety of the show's run from 1997 to 2003 (via IMDb). Only two years after the ending of "Buffy the Vampire Slayer," Hannigan would take on the role of Lily Aldrin in "How I Met Your Mother," a 10-time Emmy Award-winning series that gathered a massive fanbase over the years.

Throughout the early 2000s, Hannigan got a few other supporting roles and guest spots in movies like "Boys and Girls," "Rip It Off," and "American Wedding." However, television was still where the actress excelled. In the middle of her run on "Buffy the Vampire Slayer," she appeared in its spin-off "Angel" as Willow, along with dabbling in voice acting on "Rugrats" and "King of the Hill."

Just before Hannigan landed her iconic role in "How I Met Your Mother," she appeared in a small role that you likely forgot about.

Alyson Hannigan played Suzy Simpson on That 70's Show

Alyson Hannigan appeared in "That 70's Show" in 2004 for a two-episode run as the character of Suzy Simpson in "Sally Simpson" and "Won't Get Fooled Again" from Season 6. In the show, Suzy is a fellow police cadet from the academy where Kelso (Ashton Kutcher) is training, and she develops a crush on him. However, Kelso isn't interested, but Fez (Wilmer Valderrama) certainly is. Kelso makes a misguided effort to set Fez and Suzy up, which doesn't go over well as she believes she's on a date with Kelso. 

This was a relatively short-lived character for Hannigan, but the draw was likely to be part of another popular series. However, Hannigan doesn't talk about her guest spot on "That 70's Show" much. In a recent interview with Buzzfeed reflecting on her career, Hannigan explains how "Buffy the Vampire Slayer" and "How I Met Your Mother" were incredibly special roles.
