Last month, Fun. promised that the video for "Some Nights" — the follow-up to their chart-topping breakout "We Are Young" — would be "amazing," which was a pretty big statement, considering they hadn't even come up with a concept at the time.

But now, all that has changed. Because when MTV News caught up with the guys last week to discuss their upcoming performance at the 2012 MTV Movie Awards, they let it be known that not only have they settled on a treatment for the "Some Nights" clip, but that, yes, it is going to be as amazing as promised.

"The 'Some Nights' video is coming; we're going to start filming it next week," frontman Nate Ruess said. "We're going to try and get it out as soon as possible. It's been really rough, because we've been on tour for the last two months, so we found a night off — that was all we get, and we have to rush to a show the next day — but I know we're going to make the most of it, because the director has a brilliant concept and it's something that doesn't put as much pressure on us, other than just to perform and perform well, and he's going to set an amazing scene around us."

And while Fun. wouldn't reveal all the details about the video, they did let a few plot points out of the bag — namely, it's going to be a nocturnal affair ("There are lanterns," Ruess said) and there will most definitely be a xylophone in play. Other than that, though, well, you'll just have to wait and see.

"We're filming it through the middle of the night," guitarist Jack Antonoff said. "And Andrew [Dost] is going to be walking with a xylophone at some point, not to give away too much."

"Now, you're giving away too much," Dost laughed. "All right, fine, I'm walking with a xylophone."

The 21st annual MTV Movie Awards air live Sunday, June 3 at 9 p.m. ET/PT from the Gibson Amphitheatre in Universal City, California.
