These days, every period piece - American or British - is automatically compared to "Mad Men." But, other than the fact that "The Hour" has an extremely cool look and feel, there's absolutely no comparison.
Executive producer Derek Wax said he thinks "Mad Men" is "brilliant" but that "The Hour" "wasn't in any way really inspired by that show.
"We think felt that postwar Britain and this sort of extraordinary year of 1956 was rich and resonant enough to have its own dramatic sort of flavor. I think completely different in terms of characters and the flavor from "Mad Men."
Abi Morgan, who wrote "The Hour," is also a fan of "Mad Men." But she's not necessarily a fan of the comparisons.
"I think it's kind of a bit of bum steer for us because, ultimately, I think we're looking at a political thriller," she said. "And I think it just has a completely different pace to 'Mad Men.'"
But production designer Eve Stewart put it best.
"I think a lot of ['The Hour'] characters would have loved to work in the advertising office of 'Mad Men,'" she said, because it shows "the real aspirational side of the UK where we go, 'America's all great and big and shiny, and here we go.' And in fact, you're all held back by tea pots and rather bad plumbing. That's what we wanted to show.
"I think that we achieved it."
