It seems like just yesterday when Seth Rogen and Zac Efron engaged in a battle of wits in the 2014 comedy Neighbors, which became one of the surprise hits of the summer, taking in in more than $270 million worldwide from just an $18 million budget. Both actors return this summer, alongside Rose Byrne, in the upcoming sequel Neighbors 2: Sorority Rising, and to help ring in the new year, Entertainment Weekly has the first official photo. The image features both Seth Rogen's Mac Radner and Zac Efron's Teddy Sanders going topless, while Mac's wife Kelly (Rose Byrne) is wearing a cheerleader outfit.

While the photo appears to depict some sort of a party scene, we don't have any further details, like why Seth Rogen has "abs" painted on his chest. EW reveals that some of the parties fans will see in the sequel include a "disorienting hall-of-mirrors rave" and a "down-and-dirty Mad Max-inspired tailgate". It's certainly possible that this photo is from the tailgate party, but there aren't exactly any cheerleaders in Mad Max: Fury Road, so we're not completely sure. At any rate, Seth Rogen revealed that being shirtless around Zac Efron isn't exactly a pleasant experience.

"That one was both a lot of fun and a nightmare to shoot. Anytime I'm shirtless next to Zac Efron for really long periods, it even gets to me eventually."

Last year's Neighbors ended up with the married couple Mac and Kelly eventually getting the best of Teddy and his fraternity, but in the sequel, they have a new problem to contend with: a sorority that moves in on their block. Chloe Moretz and Selena Gomez star as two of the sorority members, but it isn't exactly clear how Teddy fits into the picture. Rose Byrne revealed that the emergence of this sorority has both Mac and Kelly fearful for their daughter's future.

"With the sorority girls, it's like a glimpse into their daughter's future, and it terrifies them."

Seth Rogen also co-wrote the screenplay for this sequel, with his writing partner Evan Goldberg and original Neighbors writers Andrew J. Cohen and Brendan O'Brien. Nick Stoller is also back in the director's chair, revealing that his experience on both these movies has made him an expert on how to throw a "fake party." Here's what the filmmaker had to say below.

"I could do a TED talk on how to throw a fake party. I've thrown at least 20 times more fake parties than real parties, and my real parties are so much worse."

Other returning Neighbors stars include Dave Franco, Lisa Kudrow and Ike Barinholtz. Universal has set a May 20, 2016 release date for this comedy, which goes up against The Angry Birds Movie and The Nice Guys. With the arrival of this photo, the first trailer could be just around the corner, so stay tuned for that. In the meantime, take a look at the first Neighbors 2: Sorority Rising photo, and let us know what you think.
