'Harry Potter' star Mark Williams to appear on 'Doctor Who'?

Mark Williams has reportedly won a role in the next series of Doctor Who.

The sci-fi drama is currently filming its seventh run in Wales, with Harry Potter actor Williams having been spotted on set during filming of episode two.

Recording recently took place inside a private house in Church Road, Penarth, with resident Grace Jenkins charting the shoot on Twitter.

"Living room has been cruelly disfigured so they can film Doctor Who in it," she wrote. "Rory and Amy Pond's wedding photos are now on my living room wall and will be all weekend as they're filming Monday [February 20]."

Jenkins later posted a photo of herself with Williams, referencing the actor's Harry Potter role: "I just met Mr Weasley!"

In addition to the Harry Potter films, comedian and actor Williams is known for appearing on BBC sketch series The Fast Show and currently plays a recurring role on Being Human.

Doctor Who will return to BBC One in the autumn.
