Couple Let Johnny Knoxville Crash Their Wedding For 'Bad Grandpa'

Would you let notorious Jackass prankster Johnny Knoxville come to your wedding? How about letting him crash your reception as part of his latest bad taste movie, Bad Grandpa?

An L.A. couple let Knoxville (in makeup as his Bad Grandpa character) use their wedding at the Wattles Mansion as a backdrop for part of the hidden-camera comedy.

It didn't hurt that the groom, Jarrod Brom, was a producer on the film, or that his bride, Kim Peeler, was unusually game to let their August 2012 wedding be part of the movie. "Let’s have them prank our wedding! How awesome would that be?" she told Huffington Post.

The production company decided to have Knoxville prank a few guests during the post-ceremony reception, instead of interrupting the wedding itself. (The gung-ho bride actually wanted him to shout out, "I object to this marriage! I'm sleeping with the groom!" but got shot down.)

The wedding party was in on the joke but not the guests, who reacted understandably to a rowdy old man who knocked over the stack of champagne glasses and the wedding cake, with his "grandson" then munching unceremoniously on a sizable chunk.

Peeler said did have second thoughts at one point, but decided it was all worth it. "It hit me that this is really going down, like for real, this is going to actually happen," Peeler said. "A Paramount movie has taken over our wedding. It’s going to look like a million bucks in addition to being a story to tell the grandkids. I loved it."

She said she was too focused on the wedding itself to be distracted by the fact that it was all being filmed for a movie. "We laughed, we cried, and we were able to forget about the dozen cameras perched and waiting to capture a crazy cake stunt."

The movie opened this weekend, knocking Gravity off the top of the box-office charts.

The scenic Wattles Mansion, which is located at 1824 North Curson Avenue, was also used in Mariah Carey's video for "We Belong Together," in which she's tying the knot with Eric Roberts, then ditches the groom for Wentworth Miller.

The mansion was built in 1907 by wealthy Omaha, Nebraska banker Gurdon Wattles as a winter home. The property has since been split into three areas: the Wattles Mansion, Wattles Park and Wattles Gardens. The mansion has been used in productions including The O.C. and Buffy the Vampire Slayer (as the frat house in "Reptile Boy"), Troop Beverly Hills, and the sanitarium scenes in Rain Man .
