Adam Demos Says It Was Hard for Him to Stop 'Stop Laughing' While Filming 'Spa Weekend': 'That Was the Challenge'

Adam Demos admits it was tough to keep it together while filming the upcoming movie Spa Weekend, which stars Leslie Mann, Anna Faris, Isla Fisher and Michelle Buteau.

"I mean, it was equal parts the [most fun] experience, but also the hardest, because they’re so funny. I couldn't stop laughing during the takes. That was the challenge, but, I mean, what a gift. If my biggest problem was laughing too much, then it was one of the best jobs," the handsome hunk, 41, exclusively told OK! on August 18, when Soma partnered with Black Bear Studio’s newest film, Spa Weekend, to host an advance screening for VIP guests.

Demos added that the ladies are some of the "best" to ever do it in comedy, adding that he's "lucky" he got the role of an eye-catching yoga instructor who falls for Mann's character, Jane.

"I think it’s nice to see me go sort of toe-to-toe with Leslie in these scenes, and you can see a little bit that there’s a little improvisation in the moment. And it was a different — it was a step up for me, comedically, and I feel like I’m proud of what was on screen," he shared. "Have a ball, have a drink, bring your friends, go solo, it doesn't matter!"

The comedy follows three best friends, Jane (Mann), Coco (Buteau) and Sophie (Faris), "as they embark on some much-needed pampering during a luxury spa break in Palm Springs. But when their trainwreck friend, Mel (Fisher), turns up, the relaxation quickly descends into chaos with hilarious consequences," per the synopsis.

The ladies were equally excited to be part of the film.

“I couldn't believe that we were able to make it. Truly,” Faris told Bustle. “Even as we were getting closer and closer to what we were told was the start date. I was like, Oh my God, they’re gonna make that!”

Fisher added, “I try to make movies that I want to see. I loved Bad Moms. I love female-driven comedies. Loved Bridesmaids. I love everything on Netflix that has a row of ladies. I’m gonna watch it. I’m there for it. So it’s fun to do something that you want to see, and you have an appetite for because it means that you are tapped into the audience.”

On Tuesday, August 18, the cast made a surprise appearance to welcome guests and introduce the movie, which opens August 21 nationwide.

Soma hosted a fun girls' night out featuring an exclusive screening, a first look at the brand’s newest Vanishing Collection, personalized Bra Quick Fits, photo moments and more.

Soma believes self-care begins with feeling comfortable and confident in your own skin. Whether that means finding the perfect-fitting bra, treating yourself to something new or enjoying a night — or weekend — away with your closest girlfriends, taking time for yourself matters.
