Cleary not in this case. Movie rights are a bit different to a spin off and the BBC holds that afaik.

You may also have heard rumours about the Time Lord hitting Hollywood... We can confirm that a Doctor Who feature film remains in development with BBC Worldwide Productions in Los Angeles. However, there is currently no script, cast or production crew in place.
We'll bring you any significant movie developments as they're confirmed, but right now there's a lot more Doctor Who coming your way which is imminent and incredible... You'll get a glimpse of what we mean when we release the first image from the amazing Christmas Special later this week!

So officially it is in development but still really early on.
