"your" = "you're"

"The movie dripped with a cool 40s art style, with enough odd looking modernizations to make it all work. It wasn't steam punk. It wasn't art deco. It wasn't historically accurate. But it was awesome. Every aspect of the world was wonderfully realized to give us a parallel WWII that I totally bought into."

The style name your looking for is "dieselpunk."

It's like steampunk, but rooted in the years between WWI and the bombing of Hiroshima.
