Warren Brown and Matthew McNulty are to guest star in 'Doctor Who'.
Warren Brown
The former 'Luther' actor and the 'Versailles' star will feature in an upcoming episode of the sci-fi show in a storyline that will see the human race come under the threat of extinction, but details of their characters are being kept under wraps.
Warren was thrilled to learn he'd be on the show - but admitted it was tough keeping it a secret.
He said: "I was on such a high when I got the call from my agent, then such a low when I had to keep it top secret and couldn't tell anyone! I can honestly say though it was and has been one of the most fun jobs I've ever had to date!
Matthew "had a blast" shooting his scenes alongside current Doctor Jodie Whittaker.
He said: "I had such a blast filming the episode and couldn't ask for anything more for my Doctor Who debut."
Show bosses were delighted to get the pair on board.
Matt Strevens, Executive Producer of the sci-fi drama added: "We are totally thrilled to be welcoming Matthew and Warren to the cast.
"Their talent and versatility sets this action adventure alight."
The BBC recently confirmed a guest appearance from 'Breaking Bad' actress Laura Fraser in an episode titled 'Orphan 55'.
And Laura admitted she felt honoured to be starring in the "iconic" show, although she was very nervous because she'd always been such a fan.
She said: "I was quite nervous because when there's a show that you've watched as a child that is so iconic and almost out of reach in your head because when you were a kid watching, it just seemed like it would be inconceivable that you could ever actually be on that TV show,
"It was really exciting. There were so many lovely and funny people and we were travelling around quite a lot to different places in these outrageous costumes and being silly and telling stories and having a laugh."
