According to Deadline, former doctor Matt Smith has joined Screen Gems’ upcoming zombie-ish movie Patient Zero. Smith will play the lead, a man who is “inexplicably immune” to a “super strain of rabies” that has transformed a bunch of people into—let’s just be honest here—zombies. Deadline doesn’t say they’re zombies, and Screen Gems might not admit they’re zombies, but come on. It’s a “new species driven by violence.” They’re zombies. Smith’s character can somehow communicate with the monsters, so he leads a mission to find the titular “patient zero.” Doing this will somehow help him cure the zombie virus and save his infected wife, but he’ll probably have to tap into all of the medical knowledge he picked up in his years on Doctor Who in order to pull it off.
