This post contains spoilers about an end credits joke in "We're the Millers."
One of the funniest moments in "We're the Millers," the new R-rated comedy that has grossed $38 million during its debut week, is a group sing-along to the TLC song "Waterwalls" from characters played by Jason Sudeikis, Jennifer Aniston, Emma Roberts and Will Poulter. That moment makes a return during the film's de rigueur closing credits outtakes, but with a twist: Instead of "Waterfalls," Sudeikis, Roberts and Poulter break character and serenade a bemused Aniston with The Rembrandts' "I'll Be There For You," a.k.a. the "Friends" theme song.
"That was something that Jason and I came up with together," director Rawson Marshall Thurber told HuffPost Entertainment. "I forget who said it, but we all started laughing really hard."
For Thurber and Sudeikis, the issue wasn't if the prank was funny, but whether Aniston would find the gag as amusing as its perpetrators. "There was that moment where you're like, 'Gosh, I hope she takes this the right way.' Because you never quite know."
Fortunately, she did. "She really loved it," Thurber assured HuffPost Entertainment. "She laughed and clapped. You see her reaction on camera -- it's kind of begrudging laughter, but she was a really good sport about it. She poked me and Jason in the ribs afterward like, 'You got me.' It wouldn't be in the movie if Jen wasn't happy with it."
"We're the Millers" includes numerous moments when the cast looks like it's having a great time, among them, an R-rated game of Pictionary, an almost-foursome and a faux-threesome, but Thurber said the "Friends" outtake was the shoot's highlight. "That was one of the funniest moments we had. Fortunately we were rolling the cameras when we did it. It just seemed like a nice tip of the cap to the audience. Like, 'Here you go. We had a good time, we hope you did too.'"
"We're the Millers" is out now.
