all BBC shows turned into films, and with AbFab and Mrs Brown's Boys, it was BBC Films that made them! There is no reason why Doctor Who couldn't be made into a film. They could make any number of films surrounding the 8th Doctor's adventures. Fans aren't stupid. They'd know the difference.”
I knew I shouldn't have been so lazy with my previous post. I was anxious to keep it as concise as possible (I'm known to write horribly long-winded posts). I'll try to make it as simple as possible, mostly to prevent my tired brain from killing itself. (I'm on night shift so it's well past midnight now.)
We need to consider this question: Who's the copyright holder?
I'm willing to bet that all those you listed weren't/aren't owned by the BBC. They commission a TV series, sometimes make it an in-house production and broadcast it, but it doesn't mean they actually
own the concept. This usually belongs to whomever created or devised the concept. In some cases, creators sell their ownership to the BBC and in other cases, they don't. It varies from one to another.
For example:
The BBC doesn't own Absolutely Fabulous itself. The TV series themselves belong to the BBC, but not the concept of it. As far as I know, it's currently owned by creator Jennifer Saunders (and maybe Dawn French if she hadn't sold her share to Saunders yet), which gives her a right to option or license it to a third-party. Any production company. This includes BBC Films.
When the BBC does own a concept, they usually aren't allowed to adapt it for the big screen. I actually don't know why. So many gave me different explanations on how the stipulation came about. I don't know which is accurate, I'm afraid.
I hope that makes sense. Sorry for not being that great in being articulate, though. Thanks.
