Saw a movie today that fits in this thread. The Whisperer in Darkness
, made in 2011. That's right, only 2 years ago. But it's a masterful job of recreating the style of science fiction/horror movies of the 30's. Not just the fact that it's filmed in black and white, but the lighting, camera shots and even the actors all look true to the period. Only a couple of video effects towards the end give it away (along with one anachronistic prop)
Based on the H.P. Lovecraft short story of the same name. I came upon the movie about 1/3 of the way through and had to double check the listing a couple times to make sure I was actually watching the right movie. A really excellent job.
