Via SCI FI Wire:
“A sometimes psychedelic, often twisted and always outrageous take on the book, Tin Man is the epic tale of DG (Deschanel), a young woman plucked from her humdrum life and thrust into the Outer Zone (the O.Z.), a fantastical realm filled with wonder but oppressed by dark magic. DG seeks her true identity, battles evil winged monkey-bats and attempts to fulfill her destiny.”
There’s other information, but this sounds strange … a little like American McGee’s Alice kind of strange.
