Willow Rosenberg has been played by at least two actresses. She did not appear in the 1992 movie created by series creator Josh Whedon, and when the movie was revamped into a series she was played in an unseen half hour TV pilot by Riff Reagan. The pilot wasn't a smash with network execs who requested Reagan be replaced. Eventually 23 year old Alyson Hannigan was cast, and she portrayed the role from 1997-2003 (the full run of the Buffy TV series). Hannigan also reprised her role in a few episodes of the Buffy spin off Angel, later cancelled after 5 seasons.
