See photos of Zooey Deschanel and Joseph Gordon-Levitt from our (500) Days of Summer viewing party

One decade and one week after (500) Days of Summer premiered at the 2009 Sundance Film Festival, Zooey Deschanel and Joseph Gordon-Levitt watched the beloved indie together again for EW's romantic comedy-themed Untold Stories issue. See all the exclusive photos from their groovy shoot ahead.

Regina Spektor's "Us," which opens the film, played as the stars arrived at the shoot. "I know this is on the soundtrack, but this is not something I associate with [the movie]," Deschanel said. On the set, "we were blaring Marvin Gaye."

"I forgot how chopped up it is!" Deschanel said as the film began. "I think that it's strategic, when everything comes... You get the heartbreak first, so then you view the romance with a little bit of a catastrophic bent."

Deschanel and Gordon-Levitt used the viewing party to campaign for #JusticeForSummer, whom they both believe is very misunderstood. "The movie is constantly drawing you into Tom's perspective, very much," Gordon-Levitt said. "[But] Summer is the one who is honest — much more than Tom is, actually."

"The band's back together again!" Deschanel cried as she and Gordon-Levitt watched themselves sing karaoke onscreen. (Check out the full viewing party for their account of Gordon-Levitt's curtain-ripping, "full commitment" real-life karaoke story.)

"Summer repeatedly tells you her point of view," Deschanel says, but still viewers side with Tom, despite how much he disregards her honest expressions of what she's looking for. "But she has the traditional male point of view and he has the traditional female point of view in this movie — and the traditional female point of view is more romantic."

"I think it’s a common thing, especially in romantic comedies, that it’s just okay to lie," Gordon-Levitt said watching the movie. "[But] if you’re trying to solve love life problems, almost always the answer is just be honest."
