There's several Weird War II movies due out over the next year or two:
Probably the best-known right now is
Iron Sky, which had a full-length trailer come out 2 months ago.
There's also the Polish film
Hardkor '44, which has some
absolutely crazy concept art. Apparently it's being filmed in the "CGI sets" style like Sky Captain/300/Sin City was. No idea if/when it'll come out.
Outpost II is coming out
sometime soon, and actually just got a German trailer - their facebook page says an English trailer is in the pipeline and will be posted soon.
The 4th Reich has
Sean Pertwee and Tom Savini, which means it should be pretty fun. Savini also apparently plays real-life Nazi asshole
Oskar Dirlewanger, whose
penal legion was notorious for mass-murder of civilians and rape. Real nice guy.
Panzer 88 might come out
someday. Maybe.
Project Arbiter is like Iron Man set during WWII and it's got a couple trailers. Right now it's just a 20-minute short but apparently they're hoping to shop it around as feature-length movie.
Apparently we're also getting a
The Boys from Brazil remake, which will take some heavy-duty overhauls in order for it to really "work". The original book and movie are kinda dated.
