Tennant was the 10th Doctor and Piper played his on-screen companion Rose Tyler in the BBC One show. Filming on the show, which will also star John Hurt, will start next week. Tennant’s successor, Matt Smith – also in the special with his new assistant played by Jenna-Louise Coleman – says fans “will not be disappointed” by the 3D show, due to air on 23 November.

“I wasn’t asked, no,” she said.
“I think Matt Smith may have said, in passing or in jest, it would be nice.
