Now that their work on the Muppets films has given them clearance to play with Jim Henson's toys, director James Bobin and songwriter Bret McKenzie have reportedly begun work on something of a spiritual successor to Henson's Labyrinth. "I'm in the middle of a script for a kind of--it hasn't got a name yet, but it's a fairy tale comedy musical, sort of akin to Labyrinth or something like that," McKenzie told Collider (via). "James Bobin's helping me. I'm the official writer but we're developing it. I want to make a comedy musical with singing dragons and monsters and stuff. [It's] live-action, so it would be a mixture of The Muppets and The Princess Bride." Unfortunately, while his list of things '80s kids totally love is complete, the film is still only in very early stages, so it could be a while before we determine the Goblin King surrogate of a new generation. Those are some pretty tight pants to fill.
