Despite being listed on IMDb as being amongst the cast for a future episode, the former Life on Mars star who can regularly be seen on stage and screen in the UK tweeted on Monday:
Of course this could all just be a diabolical Master-esque double bluff, paving the way for a triumphant return and possible regeneration (well, Matt Smith got a new TARDIS: why not a new Master?) for the fiftieth anniversary celebrations.
Simm himself told The One Show last summer that, if offered the chance, he’d love to return to the show.
Or it could just be someone speculating in a similar fashion to this, only using IMDb to stoke excitement levels so high (it wouldn’t be the first time…) that fans had no choice but to tweet Simm and ask him.
Whatever happens in the Doctor’s future we know that somewhere out there the Master is plotting to shorten that 900 odd year existence considerably and it’d be a crying shame if Simm wasn’t allowed one more crack at the whip upon the Master’s return.
