Roseanne with Alyson Hannigan
Willow Rosenberg in Buffy the Vampire Slayer, Michelle Flaherty in the American Pie trilogy, and Lily Aldrin in How I Met Your Mother are just a few of Alyson Hannigan’s memorable roles.
She has lent her voice to the Disney Junior comedy Fancy Nancy as Claire Clancy. She had a brief role as one of Becky’s pals in Roseanne before she was killing vampires or playing the flute in her high school band.
