Oh, we’re off to see the cardiologist!

CBS is taking a big swing with a new project with a higher-than-high concept: Wizard of Oz medical drama.

The broadcaster has inked a deal to develop a series titled Dorothy, described by the network as “a medical soap based in New York City, inspired by the characters and themes immortalized in The Wizard of Oz.”

The show is from writer Emily Fox (Ghost Whisperer) and executive producers Carl Beverly and Sarah Timberman (FX’s Justified, CBS’ Elementary) from CBS Television Studios.

When you think about it, there is a certain medical drama aspect to the classic film. Stay with me here — Dorothy’s friends are all missing some vital component that they’re on a quest to recover. She helps put the life-saving straw back in the Scarecrow and gives joint-loosening oil to the Tin Man (who then gets a “heart” from the Wizard).

CBS has experimented with crossing procedural drama with fantasy or supernatural concepts before, both successfully (the aforementioned Ghost Whisperer) and less so (ill-fated zombie cop drama pilot Babylon Fields). Despite this spring’s Oz The Great and Powerful film, the original Wizard of Oz book has been in the public domain for decades, so CBS presumably has free reign (though there have been disputes over the property).

What do you think of CBS’ Oz trip? And who should play the wicked witch of the E.R.?
