Fancy turning back time and spending a weekend at The Halcyon, ABC's plush hotel? You're not alone. The actors were bowled over by the scale and intricacy of the set.
“If you woke up on this set you’d think you were in a real hotel," said Jamie Blackley, who plays Freddie Hamilton, the proprietor's sulky son. "It’s incredible. It’s so beautiful with lots of little details. You can go upstairs and you have the corridors and rooms. The royal suite is really beautiful. It’s like a different world. I’ve nearly fallen asleep on one of the beds. I also love the kitchen. It’s so intricate with all of the equipment.”
Olivia Williams – aka the proprietor's snobby wife and Freddie's mother, Lady Hamilton – was equally entranced by the fake hotel, which was built at West London Film Studios: “It’s pretty extraordinary and the detail is so beautiful; all the statues and every light fitting; the art work is wonderful.
“What The Halcyon has to be is a place that is a little bit magical and a little bit heightened. The outside was grey and dreary in the Blitz. And you came into the hotel and there was light, music, dancing and champagne. So we really want those scenes to sparkle. And they do.”
Of course, there are plenty of grand old hotels that are every bit as luxurious in London. Here are three that inspired The Halcyon and weren't blown up by ITV...
