other retro futuristic movie?

There is the 1991 movie "The Rocketeer". "Sky Captain and the World of Tomorrow" and "The Rocketeer" http://us.imdb.com/title/tt0102803/ are both very good are unfortunately the only retro-futuristic movies made recently. Also I highly reccommend the 1927 movie "Metropolis" http://us.imdb.com/title/tt0017136/ It is silent, but it is so good you hardly notice. It is extremely retro-futuristic, and has special effects that are so amazing that it is hard to believe that it was made so long ago. "Sky Captain and the World of Tomorrow" actually has a tribute to "Metropolis" in it. The mysterious woman is a tribute to the evil Maria robot in "Metropolis", which was also the inspiration for C3PO. I actually consider "Metropolis" to be the greatest masterpiece ever made. Many people who usually hate silent movies love it. You might also like such movies from the 1930s as "Things to Come" http://us.imdb.com/title/tt0028358/and "Just Imagine" http://us.imdb.com/title/tt0021016/, or classic serials like "King of the Rocket Men"(the inspiration for "The Rocketeer")http://us.imdb.com/title/tt0041547/, or "Buck Rogers" http://us.imdb.com/title/tt0032290/. I hope this helps.

Though it has a very different vibe, Brazil is also retro-futuristic. Its setting is sort of non-time that looks like a cross between the 40s, the 80s, and some ugly, Orwellian future.

This sort of thing kind of borders on alternate History, like Fatherland, too. Fatherland is set in an alternate 60s, where Hitler won WWII, eventually signing for peace with President Joseph Kennedy. The story is a murder mystery sparked by an American reporter visiting German occupied France (if I remember right), and an SS officer (now the German equivalent of the FBI). I've heard the book is amazing, but the movie was really good, too.

Another you might enjoy would be City of Lost Children, a french movie set in another sort of non-time. It's a bit more fanciful, but very cool.

Unfortunately, the place where this sort of story seems to be done most is in anime, and I can't stand anime, so I don't have any real recommendations.

I love this kind of genre and I find it strange how there isn't much out there that's like this from what I know.

I have yet to see the original Metropolis so I don't know if this one is the same story but it was amazing, don't get turned off by the fact that it's an animation for it was drawn fairly cartoony but the story, the scenery and the soundtrack was good and overall was very enjoyable! http://www.imdb.com/title/tt0293416/

Overall I'd say we'd have to dig for the old black and white films. I wouldn't even know what category this goes under but I guess it would be a sub-category of sci-fi and there are some lists imdb http://www.imdb.com/list/PIca5-_2p5Q/

The movie actually looks a lot like the Disney afternoon cartoon "TaleSpin", but with people instead of animals.

Other borderline possibilities:

Meet the Robinsons
The City of Lost Children
Robots
Flesh Gordon
Barbarella

You've got to see Cory McAbee's The American Astronaut:

http://www.imdb.com/title/tt0243759/

It's an utterly independent steam punk sci fi western cult classic...with tons of kick ass original music and truly surprising SFX. Permanently lodged in my top ten adventure flix of all time!!
