The 2014 comedy hit Bad Neighbours was jam-packed with raunchy humour - but one very graphic sex scene ended up being too much for audiences to handle.
The film, which later spawned a 2016 sequel, told the story of a thirty-something couple (played by Seth Rogen and Rose Byrne) locked in an escalating turf war with the rowdy fraternity house next door (led by Zac Efron and Dave Franco).
As tensions rise, the couple enlist their best friend Jimmy, played by comedian and actor Ike Barinholtz, to help them get revenge on the frat bros.
In a new interview with Howard Stern, Barinholtz details one scene that ended up on the cutting room floor in which he settled a score against fraternity member Scoonie, played by Christopher Mintz-Plasse (best known as Superbad's McLovin').
"In the movie he f**ks my ex-wife, so we're at war, an escalating war," he says.
In the film's original ending, Scoonie is in his dorm when he gets an email with a video attached. He opens the video to see his mum - played by Megan Mullally of Will and Grace fame.
"She's like 'Hi honey, hiii!' And then I lean into frame and I'm naked, and I'm like 'What's up dude, I'm gonna f**k your mum right now'," Barinholtz.
Sure enough, Jimmy starts to get hot and heavy with Scoonie's mum on camera, until another figure enters the frame: Scoonie's dad. He's played by Parks and Recreation actor Nick Offerman - Mullally's real-life husband.
Here's where things get real freaky: Dad jumps right on in. It was, Barinholtz says, a very interesting day at work.
"For like two or three hours we shot this super-hardcore sex scene with me and Megan Mullally and Nick Offerman. And I mean, it was f**king crazy. I have the back of her ankles on my shoulders, he's got this big prosthetic d**k ... It was f**king crazy," says Barinholtz, who goes into even more vivid detail in the original interview.
This would serve as the film's big climax (pardon the pun): Jimmy sleeping with both of his rival's parents in the ultimate act of revenge.
"The whole time I'm like: This is the last thing they're gonna see in the movie. This is so cool and punk rock!"
There was one problem: Audiences loathed it.
"They shoot the movie, they test the movie, and then the director Nick Stoller calls me and says: 'Hey I just wanted to let you know that the ending with the three-way tested lower than anything I've ever been involved in. We're cutting it from the film and it'll never be seen'."
"The audience hated it; they uniformly thought it was awful and gross."
Something for the Director's Cut, perhaps?
