Hey Captain America fans! If you have plans tonight, cancel them! MTV News is proud to present another exclusive "MTV First," with none other than the Cap himself, Chris Evans, as our special guest. At 7:57 p.m. ET, tune into MTV and MTV.com, where Evans will be on hand to present a new clip from the movie, and then stick around for a 20-minute Q&A on MTV.com, streaming immediately afterward. We'll be discussing all things Cap and answering the questions you submitted.

Among a wide range of topics, we'll talk to Evans about what it was like to put on those iconic Captain America costumes. And just to give you a little preview of what's in store, we've got a snippet here, so read on (and click the embedded video).

"I did not get to keep any of the costumes, unfortunately," Evans told us. "Because a lot of times on films you have to go back to do re-shoots, and if they don't have the suit available, we're in trouble. And no, they were not comfortable," he added.

Regarding the evolution of Cap's famous red-white-and-blue ensemble, Evans revealed that the next time we see him post-"Captain America: The First Avenger" -- alongside a slew of fellow Marvel superheroes in "The Avengers" -- he'll be rocking a more modern suit.

"In 'The Avengers,' the suit is much more slick, it's modern. There is a lot of range of motion and it makes those fight sequences a lot easier," Evans explained. "It looks fantastic."

For more from Evans, tune in tonight to MTV and MTV.com at 7:57 p.m. ET.
