Goran Višnjić is establishing himself as a mainstay in genre TV shows these days. He has appeared in recent fan favourite shows like Timeless, The Santa Clarita Diet, the upcoming second season of The Boys, and now the upcoming series of Doctor Who. He and veteran actor Robert Glenister are both joining BBC's Series 12, along with Lenny Henry and Stephen Fry.

For Višnjić, it's about what it means to go from fan to family member: "I've always been a huge fan of Doctor Who, so when the offer to play one of my favorite people in history came, it made me so happy to be part of the show and it turned into this awesome, dream job!"

Executive producer Matt Strevens believes it is a testament to the show that actors of Višnjić's caliber want to be a part of it:

"One of the great joys of Doctor Who are the legendary actors who want to come and join in the Doctor's adventures. We were thrilled to welcome Goran and Robert, whose worked we've loved and admired for years. They create two iconic characters who are going to delight and entertain."

So who is Višnjić going to play on the show?

I'm calling in some mindless speculation now:

He's playing Nikola Tesla.
