'Doctor Who' Season 12, Episode 4 Recap: "Nikola Tesla's Night of Terror"

After nearly 60 years, Doctor Who finally gets around to visiting a historical figure which one would have thought would have turned up already: Nikola Tesla (Goran Višnjić). The Serbian-American inventor was the father of A/C current, best known for his electrical and mechanical engineering inventions and his futurist view on the world. He's also famous because of what he's not credited for: The lightbulb. It is popular lore Telsa invented the lightbulb first. He just couldn't capitalize on it, and then Thomas Edison beat him to the punch and became synonymous with electricity.

Graham: "Don't worry, this ain't our first rodeo."
Ryan: "We've never been to a rodeo."
Graham: "You're not helping, Ryan."

With such a background, one would have thought The Doctor would have popped round to see the guy before. And a quick dive into Whovian lore shows Telsa is a favorite of Seventh and Eighth Doctor, but only in radio plays and books. This is the first time the Doctor has crossed paths with him on screen.
