Director Joe Johnston (The Rocketeer) and screenwriters Christopher Markus & Stephen McFeely have delivered a "note perfect" movie rendition of the origin of Captain America: The First Avenger. Actor Chris Evans absolutely nails the role of Steve Rogers, the skinny but plucky reject who repeatedly gets written off as being unfit for military service, and then volunteers for a top secret research project that turns him into the star-spangled superhero dedicated to defending America's ideals during World War II. It's the key aspect of this particular character that Steve Rogers was "Captain America", before he underwent the super-soldier transition, and that's why this film works as well as it does. The inner quality of the man informs the character of the hero. This is the very thing that Dr. Erskine saw in him to begin with. Evans is topnotch, and damn, do they really work wonders in the CGI-process that altered his physical appearance into a 90 lb asthmatic. Wow!
Trailers have clearly established that the bulk of Cap's origin and story occur during the "big war", but the framing sequence set in the modern era is ideally realized too. Everything from the score, to the special effects, costuming and performances just gets it "right" from start-to-finish. And I've got to say that the ending is PERFECT. Look for cameos, both expected (Samuel L. Jackson) and one subtle glimpse at a character who was originally a WW2 ally of Cap's.
I could ramble on, but doing so would likely veer far into spoiler territory, so just go SEE this terrific movie and enjoy it for yourself. Captain America: The First Avenger is easily one of the best superhero films ever made. I'm really proud of Johnston and the guys for not screwing this one up. The "King" would be proud. Highly recommended!
