I've been enjoying a rewatch of this and it's entirely down to Hilary,head and shoulders the funniest dumb blonde I've ever seen in a comedy and Rebecca Lacey managed to portray her as endearing rather than a laughing stock and got all the big laughs.
I thought the 2 Zoe's were much of a muchness and I've no idea why Alec was Scottish didn't even have a comedy kilt wearing scene
