I'm guessing you're not a "Doctor Who" fan. If you were, you'd have immediately recognized David Tennant, who played the Doctor from 2006 to 2008. 

I hate to sell him short, as he's an incredibly accomplished actor in his native Britain, but most North American viewers know him as the 10th Doctor. There are other possibilities, however.

For example, you might know him as the demon Crowley in the ongoing Amazon series "Good Omens," or as the villain in the first season of the Netflix Marvel comics series "Jessica Jones" in 2015.

Or maybe you were able to spot him amid the cavalcade of British stars in 2005's "Harry Potter and the Goblet of Fire," playing the villainous Barty Crouch Jr. This was a relatively small role in an enormous movie — very much akin to his "Mary Queen of Scots" turn in 2018. But again, his biggest work was made specifically with British audiences in mind.

He starred in the critically acclaimed detective series "Broadchurch" from 2013 to 2017 and in the lavish BBC historical miniseries "Spies of Warsaw." He's also spent a lot of time doing "Doctor Who"-adjacent work, showing up on spinoffs of the show, documentaries about it and comedy spoofs of it.

I don't mean to keep returning to "Doctor Who," but Tennant does it, too. It was recently confirmed that he'll reprise his role as the Doctor in the show's 60th-anniversary special next year.
