Since it aired last night on CW, I thought it'd be a good idea to re-open the Easter Theatre with Here Comes Peter Cottontail, which Rankin-Bass adapted from the book, The Bunny That Overslept, in 1970.
Peter (Casey Kasem) is in the running to be the new Easter Bunny when Colonel Bunny decides to retire. However, January Q. Irontail (Vincent Price) schemes to claim the title for himself by any means necessary, and sends Peter on a wild calendar chase, if you will. Helping Peter out is peddler-magician Seymour S. Sassafrass, who also is our narrator (and voiced by Danny Kaye), and Antoine, a caterpillar (Kaye again, using a French accent), who morphs into a butterfly at the end of the story.
Bearclaws Village uploaded a digitally remastered version, which probably is the same one you might've seen last night.
Delightful fun, but unfortunately, its airing on CW was the first in a looooooong time.
