Sci Fi offers comic prequel to 'Tin Man'

Sci Fi Channel made a big push at Comic-Con this year for its December-airing miniseries "Tin Man," a kind of edgier retelling of the "Wizard of Oz" starring Zooey Deschanel, Alan Cumming, Neal McDonough and Richard Dreyfus.

To promote the upcoming event, they've commissioned a prequel comicbook from writer Stuart Moore and artist Siju Thomas. Some printed versions were handed out at Comic-Con — one of many TV shows using comics as promos — but the main rollout will be on Scifi.com and cellphones sometime soon. Here's a sneak peek at the cover and a few inside pages. (Click on the images for a closer look; more after the jump.)
