The 1981 flop Neighbors infamously inverted the key character traits of its comic leads, casting wild man John Belushi as an uptight suburban straight outraged by incomer Dan Aykroyd's zany lifestyle. Nicholas Stoller's Animal House-inflected romp (also entitled Neighbors in the US) repeats this riff, with Seth Rogen as a domesticated father/husband butting heads with Zac Efron's untamed party animal.

While the results may be nothing like as disastrous as Belushi's parting shot, this still lacks the discipline necessary to make it anything more than a war of improv attrition. Too often we're left with the sense that the cameras just kept rolling while the talented leads (Rose Byrne adds a touch of class) amused themselves in increasingly shouty fashion. A recurrent slapstick sight gag about stolen airbags would be funnier if all of its punchlines hadn't already been blown by the trailer.
