BS: OK. And you said the presenters have to stick to a fixed script so.
ER: There's 2 there's 2 parts to it. With the planetarium the narration is recorded. So the first 10 minutes or so that'll be done by a narrator. So it's just a case of pressing play on the DVD. And it runs. That's that's the bit that I'm talking about the script - being the words said every single show. The second half then is the presenter's tour of the night sky, showing certain things. For that in the presenter's notes I'll give a suggested flow, things that I want them to talk about. So for example with Mars, I will definitely say look talk about where Mars is, how bright is it, which constellation it's in, how to spot it, how to tell the difference when you when you're looking at them between planets and stars. But a lot of it will actually be up to the presenter. I'll give them suggested flow. I'll give them, all the stuff that, that I would do if I was presenting the show, but that's not, in stone. If you - I I found that if you enforce a presenter to do something exactly - as you want it they don't put any of themselves into a show. And it's so much - more interesting for the presenter to put a bit of themselves into the show, but also far more interesting for the audience, if you can actually hear, because you can't see them, but if you actually hear the presenter's enthusiasm. And a certain way to kill their enthusiasm is to say "this is what I want you to talk about exactly like that."
