This is relevant to my interests—and not just because I was in my high school's production of Once Upon a Mattress. See a young Zooey sing "In a Little While" with Glee's Matthew Morrison.
Man, the 90s were cruel to everyone. Or is it made-for-TV movies I'm thinking of? Either way, I bet this is one tape from the vault that neither actor ever wanted to see again. UPDATE: a quick imdb search shows that this was made in 2005. Say it isn't so!
In case you want to start the movie (which is an updated version of the Princess and the Pea) from the start, watch here.
