The Shirley Temple version
No, its not what you think - long after her 'Curly Top' days, Shirley Temple Black had a deal with NBC to host a series of hour-long 'Fairy Tale Theater'-style episodes. And, the inaugural show they did was an adaptation of 'Beauty and the Beast.'
Apparently, it was filmed in full color, and was shot live. To my knowledge, the version is completely lost and no copy or print exists, although a few random news clippings can be found on Google summarizing how the show went.
But what's most interesting about this version is the cast. Claire Bloom plays Beauty, while Shirley just narrates and introduces the show (she did act in a handful of episodes but not this one apparently). The father is played by E.G. Marshall (probably best known to younger audiences for his role as the President in Superman II). And, the Beast is played by Charlton Heston of all people! Interestingly, all three were co-starring in 'The Buccaneer' in the same year the episode was broadcast, which makes me wonder if this wasn't some promotional effort the studio put them up to.
But, what I wonder even more is about Claire Bloom as Beauty. Have you seen her?

I've heard endless theories about who Belle's physical designs are based on, from Katharine Hepburn to Audrey Hepburn to Vivien Leigh to Sherri Stoner to Paige O'Hara to Judy Garland, but I've yet to see such a close match in terms of the bone structure/facial features/eye color/hair/etc. Shirley Temple's Storybook, while not all that remembered today, was quite popular when it came out, and remarkably baby boomers still talk about their memories of the show when it aired.
Because this was a live broadcast with no surviving footage to my knowledge, I rather doubt that Wise/Trousdale/Henn/Baxter consulted it directly. But is it possible they may have known about the Heston/Temple version? Or is it at least possible that the Purdums, who storyboarded the original late-eighties project in London, may at least have known about it? Bloom remains a known presence in British drama, and the drawings of Belle look even more like Claire Bloom in their depiction than in the Disney version, which clearly did derive some inspiration from their drawings of the Belle character (if nothing else). I have no idea but its an interesting thing to think about; I wish that it was on YouTube or something so the two versions could be compared. Although there is a promotional photo that survives (Claire Bloom is on the bed in the background).

Again I seriously doubt that this version specifically was a blueprint for the later animated film, but the similarities between Bloom/Belle are amazing. Its just a shame no surviving photos or footage can be found of Moses/Ben-Hur as the Beast!
