Chris Evans Explained Marvel's Secrecy and Brought His Brother on ‘Fallon’ (Video)

The “Captain America” star told childhood stories and stayed very vague about the plot of his new blockbuster

Once upon a time, Chris Evans was a ball of nerves every time he had to speak with the press or go on talk shows.

That no longer seems like much of a problem.

Evans was very much at ease and quite talkative during his appearance on the “Tonight Show” on Monday, doing his best to promote “Captain America: The Winter Soldier” despite not really being able to tell anyone anything about the movie. Apparently, he was under strict (and understandable) instructions to not give away any sort of plot spoiler at all about the movie, which opens Friday and is expected to bring in blockbuster box office numbers (it's already doing gangbusters abroad).

“Marvel is very hush hush, lock and key,” Evans said, prefacing his very vague explanation about the film's moral questions (but not plot).

“You did a great job of not explaining the movie at all,” host Jimmy Fallon cracked.

“That's what Marvel makes you do, you have to just dance around it,” Evans replied, cracking up. “It's good for the whole family. It's happy and sad and good and bad!”

To be fair, critics are doing all the talking that “Captain America” needs, giving it a 92% on Rotten Tomatoes thus far.

And in any case, talking about the movie was only one half of the appearance; Evans also brought on his younger brother, Scott, to play a game in which they answered questions about their childhood (with their mom looking on). Both are very good storytellers.
