Just watched it. Not impressed. This Sigfried was quite the dick. Much preferred the old version - and the books.
Slacker.
Samuel West, who plays Siegfried, is the son of Timothy West and Prunella Scales. Callum Woodhouse, who plays Tristram, is from The Durrells, a show with a very similar tone (I think it’s the same production company, even the titles are the same style). I don’t know the rest of the cast, aside from recurring guests like Diana Rigg and Matt Lewis (Neville Longbottom from Harry Potter).
I know Samuel West from Mr. Selfridge, another show that I really enjoyed.
