“It’s all fun and games until someone gets hurt,” the tagline reads and while it’s an appropriate descriptor for the tone that Killer Weekend (née FUBAR) is striving for, it never really hits the high notes I was hoping for.

The premise is great. A group of British friends go on a Stag do (AKA a bachelor party) to celebrate Sam (Sean Varey)’s upcoming marriage to a woman named Rachel (played by...doesn’t matter she’s not in this). On the trip are way too many characters to keep an eye on, which presents one of the film’s problems. The main core of the group, though, feels pulled from similar “white dudes dealing with problems when shit goes bad” type stories. We have Eric (Danny Kirrane), trying to do his best Zach Galifianakis as the overweight comedian of the group. There’s Myles (Timothy Renouf), who is the Bradley Cooper-in-Hangover of the group, except less charming and more annoying.

Rounding out the core group of important people is Toby (David Mumeni), the Ed Helms, father figure of the group. He’s the only one of the friends who’s married with kids. Oh and there’s Gerald (Mark Heap), the father-in-law-to-be who used to be in the military in some super classified way and who does not like his future son-in-law. There’s two other characters, but they aren’t important.

Instead of going on a typical bachelor’s weekend, Eric has set the group up with a zombie, survival-themed trip where the group of friends (and Gerald) are given paintball guns and are put in the woods to survive against a group of ex-military semi-crazy people who cosplay as zombies. Things slowly go wrong (and I mean slowly) when Sam accidentally stabs one of the “zombies” with a branch. He freaks out, thinking he killed him, but when he starts moving again, Eric, for reasons I still don’t quite understand, jabs his smuggled knife into the man’s head. When the friends freak out even more, Eric is confused and says, “let’s put it into perspective...he was already dead.” For some reason, Eric seems to think they’re really fighting zombies?

As the accidental deaths start piling up, the Stag do partiers will soon be faced with a pissed off group of killers.

The best part of Killer Weekend is the father-in-law Gerald. Mark Heap is given some fun things to work with and the way he drolly deadpans his lines provides a lot of the humor. For example, when the group of friends is talking up how fun this zombie escape weekend will be for Gerald, he responds, “it stands to reason, after a career in the military, witnessing unspeakable horrors, there’s nothing you crave more than a weekend spent running around the woods playing puerile make-believe games.” The biggest problem is that the rest of the characters are just so completely insufferable. From Myles comparing cappucino to “monkey jizz” to Eric’s desire to revert back to the high school days when they were sixteen and called themselves “The Crazy Crew,” Gerald’s “puerile” assessment feels on the mark.

I’ve seen some reviews comparing Killer Weekend to Shaun of the Dead and honestly I do not understand the comparison. This is a witless attempt at bro-comedy that’s been mined so much better in other films. As I was watching, I kept thinking back to Calibre from a few years ago that put its duo in an uncompromisingly grim situation that is in the same vein. Except that film had more to say about friendships that have maybe passed their prime and the bonds between men. I’d recommend watching that instead. It wasn’t funny...but honestly, neither was this.
