Neil Patrick Harris is known for his many TV and film appearances.

However, no one ever expected he’d join the cast of Doctor Who.

But that’s exactly what the BBC Twitter page announced on Monday.

NPH has been cast in the upcoming 60th anniversary special.

His character has not yet been announced.

Returning showrunner Russell T Davies made a statement regarding his casting.

He said, “It’s my huge honor to open our studio doors for the mighty Neil Patrick Harris.”

Although he wouldn’t reveal any details, he said, “the stuff we’re shooting now is off the scale.”

It sounds like NPH might play a villain, as Davies added, “Doctor beware!”
