Before she became Buffy and became a household name, Sarah Michelle Gellar got her big break playing the scheming Kendall Hart on ABC's long-running soap All My Children. And now that the daytime fave is going off the air, Gellar plans to make one last trip to Pine Valley, joining fellow AMC vet Josh Duhamel in returning to the show that started her career. Gellar's one-day cameo role is still TBA, since there's only room in town for one Kendall (played subsequently by Alicia Minshew)... or is there? [Deadline]
