This is pretty much your average 1930s serial action movie, where the hero Joe Skycaptain and the plucky heroine, Polly Prissypants, join forces in order to stop the invading Germans^W Martians^W Killer Robots^W^W, well, the invading whatevers from generally making earth (by which we mean America, or maybe England) an unpleasant place, and globetrotting everywhere from New York City to Rivendell to do it.
What Sky Captain and the World of Tomorrow has going for it to set it apart is that it wasn’t made in the 1930s. Sure, it has a stylistic Metropolis look to it, and the watercolor look of a black and white movie that has been colorized. But it avoids the traps of hammy acting and a special effects extravaganza that would embarrass an avid Doctor Who fan.
Mind you, the special effects don’t make the movie. CGI has gotten just good enough that you can pretend it’s not there as long as the actors aren’t interacting with it. Since pretty much the whole movie outside of the actors is CGI this time, there’s a constant low-grade awareness of it. It’s very pretty, but it’s also very CGI.
No, what makes the movie work is a delightfully convoluted plot, well written (if a little salty for 1939) dialogue, and acceptable acting from the leads. Who, despite the credits, don’t include Angelina Jolie. Don’t get me wrong, that woman can still fill out an eyepatch like nobody’s business, but expect her turn as Major “Hot Lips” Houlihan to feel more like a cameo than worthy of the shared top credit she got. So, if you’re only seeing it for her, it’s not worth the price of admission.
If, on the other hand, you’re seeing it because you have a fondness for the unintentionally campy Buck Rogers and Flash Gordon of yesteryear, or if you want that last bit of popcorn before the Oscar-bait season swings into full gear, or just because you appreciate a gratuitous cow, then this is definitely the movie for you.
