The League of Gentlemen star Reece Shearsmith has opened up about his role in the Doctor Who 50th anniversary biopic.

The 43-year-old is set to play actor Patrick Troughton (the second Doctor) in An Adventure in Space and Time, penned by League of Gentlemen co-star and co-creator Mark Gatiss.

Speaking to Digital Spy, Shearsmith said: "I was honoured to be part of it. Mark's... had that idea for a long time and he's finally got to do it this year. It's the perfect time for it to happen, with it being the 50th anniversary in November.

"I think he just always had this idea that I would [play Troughton]. It's very small - I'm literally only in a very small little bit, but it was lovely to be part of it."

Shearsmith added that he would love to appear on Doctor Who itself, but wouldn't consider himself as a suitable candidate to replace departing lead Matt Smith.

"Oh God, no! I've literally not even thought about it. I've had a few people tweeting me that, saying, 'You should be the Doctor'... I'm like, 'What?'

"It could be literally anyone. I can't imagine who we're gonna get. But it would be good to go older, I think, because they've done two younger ones."

An Adventure in Space and Time will air on BBC Two later this year.
