Alyson Hannigan
The show became a success, and Hannigan gained recognition, subsequently appearing in several films aimed at teenaged audiences, including "American Pie" (1999), "Boys and Girls" (2000), "American Pie 2" (2001), and "American Wedding" (2003). She also had a guest spot on the "Buffy" spin-off, "Angel", reprising her role of Willow in a few episodes (including most notably "Orpheus", during the fourth season of "Angel" and the seventh season of "Buffy"), but none after "Buffy" finished production.
