BBC filming in Toxteth

Okay, so it's not on stage, but it is practically outside my house. Cast and crew braved the squally weather today to film scenes for The Crimson Petal and the White. I'm told Richard E Grant was due on set today, but he's not been spotted as yet. X Files' Gillian Anderson, IT Crowd's Chris O'Dowd and League of Gentlemen's Mark Gattis also star, so could be mooching around L8 soon.
