How Neil Patrick Harris, Alyson Hannigan and cast benefited from being on the hit sitcom
Alyson Hannigan (Lily Aldrin)
"How I Met Your Mother" has provided steady work for Hannigan following her run as Willow Rosenberg on "Buffy the Vampire Slayer" -- and has further ensured that she wouldn't forever be known as the girl who did that thing this one time at band camp. Hannigan will follow up her "HIMYM" run with a starring role on the CBS comedy pilot "More Time With Family," about a husband and father (Tom Papa) who's making a career change to spend more time with his family.
