Oh, you have GOT to be kidding me
Dear Whofic author,
There is not actually any need to credit the actors when you are writing a fictional story about their CHARACTERS. Really. Truly. You don't! Trust me on this.
It's enough to cite the source material your fanwork is based on. (And make sure you say said source material isn't yours! True, we might not know if it'll actually keep one of us from getting sued. The principle is to be nice and, "borrow without permission," rather than, "steal," see.)
I mean...
You DO realize David Tennant and Billie Piper aren't actually APPEARING in your fic.
...Don't you?
Fondly facepalming,
Bean
