Look, a movie poster of Captain America punching George Bush in the jaw–like he used to punch Hitler on the old 40s comic book covers–just isn’t going to fly. You know it, I know it, the American people know it.
We need a movie that will sell. Ergo, Captain America needs to be a mutant.
A mutant with web-slinging powers.
… that turns into a big green CGI monster.
No, he said a movie that will sell tickets.
Then it’s quite obvious what needs to be done…Captain America and his Freedom Pirates of the Carribean! Starring Johnny Depp of course. 
Plus he should enroll at Hogwarths and have a quest to rid himself of a golden ring!
…on a Ocean Liner, that hits an Iceberg!
BRILLIANT!
So, we’ve got Johnny Depp onboard as Cap, Chris Tucker as Bucky, and Natalie Portman as the love interest. Kevin Spacey as Red Skull, natch.
Given the political minefield of having a black person named “Bucky”, it’d probably be safer to just name Chris’ character Battlestar instead.
Post that link for someone who didn’t read Captain American during the 80s.
Captain America needs a streetwise sidekick. Chris Tucker is proactive, and totally in my face! I love it! He brings in the…urban…demographic, and he’s so articulate!
Hitler: I will destroy America!
Depp: That’s Captain America, thank you. And you’re out of rum.
Besides, the Savage Dragon got there first (Issue 119: “BushWhacked!”) 
While the plot is important, so is the charactor. He needs to be more than the 2-Dimensional comic charactor. He needs dreams, hopes, fears, weaknesses and strengths. He needs to fail and try again. He needs to make gut wrenching decisions. Does he save his true love from the Red Skull or does he save a British division from a secret death ray? To show his humanity he needs to die. By the way I saw a Hollywood version of Captain America on some show that runs really old bad movies (Son of Svengoolie?). I don’t know how to find it. But it shows just how bad a Captain America movie can be.
I think that Cap should ride a motorcycle and have a patriotically colored motorcycle helmet. That’s a blockbuster recipe right there!
This is a brilliant start!
Better still, he should lead a team of super-specialists who pilot hi-tech airplanes and submarines with stars-and-stripes paint jobs! And – here’s the kicker – we revive a forgotten TV entertainment tradition from the early '60 – all the characters, including Cap himself, are puppets! 
Let’s see . . . what’s a good name for Captain America’s team?
BrainGlutton’s post has just awakened me to the obvious. If we want to have a Captain America movie done right, it should be done with Muppets.
No, it should be “Clutch Cargoe” style.
I say Balinese Shadow Theater is the way to go.
Mimes! MIMES!!!
