Ever seen Guillermo Del Toro's version of "The Hobbit"? How about that episode of "Buffy the Vampire Slayer" that featured Britney Spears? And speaking of Britney Spears, how did you like her album "Original Doll"?

If you're thinking, 'Oh my God, how have I not seen/heard that?', that's because they do not exist, because the world is a cruel place that refuses to bless us with good things. Or the reason may be a little less melodramatic: sometimes people just didn't get around to finishing or releasing projects, for reasons ranging from cash flow to creative drought to weird legal issues. It happens.

But sometimes it's nice to reminisce on what might have been. On Sunday, Dan Chamberlain, staff writer at The Tonight Show Starring Jimmy Fallon, posed the following question to the general Twitter public:

what's your pop culture white whale? i mean unreleased/unrealized stuff like "the day the clown cried" - mine is the rumored jay-z blueprint 3 track "crispy benjamins" which supposedly sampled regina spektor's "chemo limo"

A great question — and one a lot of people answered. Here are some of those answers, chosen either because they describe projects that really would be incredible to see in the world, or because they're just deranged enough that the world deserves to have its curiosity satisfied. Not all of these may have been legitimately in the works, but nonetheless, the ideas should arguably still see the light of day.

A Movie Version Of Sondheim's "Into The Woods" With An Iconic Cast

I just realized what mine is: that early 90s Into the Woods when they were first trying to make it into a movie.

They did a table read with Robin Williams as the Baker, Cher as The Witch, Goldie Hawn as the Baker's Wife, Steve Martin as The Wolf and DaVito as The Giant. https://t.co/3cf0CXpCMf
