The Sci Fi Channel is making a miniseries of the "Tin Man" based on the L. Frank Baum novel. The cast so far includes Alan Cumming(!), Richard Dreyfuss, Zooey Deschanel, Neal McDonough (Boomtown - how I loved thee) and Kathleen Robertson are all signed on so far. Production begins later this month.
Tales of Oz are not always my favorite, as I have been subjected to terrible Dorothy and Toto jokes ever since I stepped out of Kansas, but I imagine this miniseries could be extraordinary if it's done right.
