At this rate, Once Upon a Time may need to get in line to riff on Dorothy, Tin Man et al.

CBS has put into development Dorothy, a medical drama that will lift characters and themes from L. Frank Baum’s The Wonderful Wizard of Oz, our sister site Deadline reports.

Emily Fox (Ghost Whisperer) will pen the script and serve as an executive producer alongside Elementary‘s Carl Beverly and Susan Timberman.

To recap: Wizard of Oz. Medical drama. CBS.

Not three weeks ago, word got out that Syfy is planning its own trip to Oz, in the form of a post-apocalyptic miniseries titled Warriors of Oz. In case any of you were feeling deja vu.

So, readers…. How will such a thing work? And is there an animal hospital spin-off for Toto and the Flying Monkeys?
