Neighbors (released in some countries as Bad Neighbours) is a 2014 American bromantic comedy film directed by Nicholas Stoller and written by Andrew J. Cohen and Brendan O'Brien.

The film stars Seth Rogen and Zac Efron, with Rose Byrne, Dave Franco, and Christopher Mintz-Plasse in supporting roles.

The restrictions of parenthood make it difficult for them to maintain their old lifestyle, which alienates them from their friends Jimmy Blevins and his ex-wife, Paula.

The fraternity's leaders, Teddy Sanders and Pete Regazolli, aspire to join Delta Psi's Hall of Fame by throwing a massive end-of-the-year party.

Betrayed, Teddy leads Delta Psi in hazing Mac and Kelly, resulting in Stella nearly eating an unused condom after the fraternity dumps their garbage on the Radners’ lawn.

Failing to force the fraternity to move by damaging their house, Kelly manipulates Pete and Brooke into having sex, and Mac leads Teddy to catch them in the act.

Determined to shut down the fraternity, Mac and Kelly enlist the help of Jimmy, who is jealous that Paula is sleeping with Delta Psi member Scoonie.

To acquire evidence of Delta Psi's hazing, they hire a pledge nicknamed Assjuice to stand up to Teddy and record him threatening retaliation.

Unable to open the breaker box to restart the party and alert Watkins, Kelly shoots one of the fireworks at his patrol car.

Andy Samberg, Akiva Schaffer, Jorma Taccone, Adam DeVine, Blake Anderson, Anders Holm, Kyle Newacheck, and Jake Johnson make cameo appearances as historical members of Delta Psi Beta.

Cohen also said: "Initially, our biggest problem with the script was that it was too repetitious, and amping up Kelly’s involvement and bringing her into the war broke everything wide open.

The website's critics consensus reads, "With plenty of bawdy humor evenly spread between its well-matched stars, Neighbors earns its R rating -- and filmgoers' laughs.

[20] Critics praised Efron's performance, and noted that he had successfully shed the "Disney kid" pretty boy stereotype.

[28] On February 6, 2015, it was announced that a sequel to Neighbors is in development, entitled Sorority Rising, with Stoller set to return to direct.

Once again written by Andrew J. Cohen and Brendan O'Brien, the film follows Mac and Kelly joining forces with Teddy to take on the sorority girls who move into the old frat house.
