Wasn't this filmed exactly a year ago now?
Pretty much as there are stories from Febuary last year about it. The show must have been delayed as it was on the Autumn BBC 2 drama promo and is now coming out 4 months later.
Yes it can help a drama when the girls are pretty and the guys are quite dashing. Some people take to period drama clothes and I think, Jenna-Louise, Joanna and Janet and Angel look totally normal in them as some can just look like they are plonked in the dressed.
I wonder if Louis kills Julian and that's why he needs to get out of the country?
