Tin Man is a re-imagining of author L. Frank Baum's The Wonderful Wizard Of Oz, updated by writers Craig W. Van Sickle and Steven Long Mitchell (The Pretender). It's about a Kansas waitress called D.G (Zooey Deschanel), who finds herself transported to an alternate dimension known as "The Outer Zone".
I really enjoyed last year's Sci-Fi Channel mini-series The Lost Room, so my hopes are high for this new show, which airs in the US this December. I'd expect a January 2008 transmission on Sky One for UK viewers, if it follows The Lost Room's scheduling.
