Doctor Who: Series 13 Trailer Breakdown - 20 Things You Must See
6. Captain Jack Sparrow's Right-Hand Man
Giving Blake Harrison some stiff competition in the familiar faces category, here we have actor Kevin McNally, who is seen in a brief shot towards the end of the trailer.
Though the Brit has a long list of credits including The Crown, Downton Abbey, Supernatural, and Life On Mars, he's best-known for portraying Mr. Gibbs, Captain Jack Sparrow's trusted ally in the Pirates Of The Caribbean film series.
As is the case with Harrison, details about McNally's character haven't yet been divulged, but due to the serialised format of Series 13, it's possible we'll see him in more than one episode.
