The Doctor Who spin-off follows a group of investigators working for the secret organisation of the same name. With two series in the bag and the third season five-part special, the BBC show has proved itself to be a hit with viewers.

As to date, the sci-fi spin-off has yet to conjure up any rumours of a feature film. However season three aired in the US shortly after it did in the UK which hopefully opened more opportunities for a movie to materialise.
