Scott Derrickson has already been named as director(see "'Doctor Strange' Director Set"), and Marvel Studios is in negotiations with screenwriter Jon Spaihts for a script redraft (see "'Prometheus' Scribe to Adapt 'Doctor Strange'").
I'm all confused now. I thought there was a tv show. Maybe there's both. I'll have to do some poking around now.
But in the meantime, check out the 1978 movie Dr. Strange as posted in the comments by Wolvercote!
