While filming the 2013 indie film Drinking Buddies, which starred Olivia Wilde, Anna Kendrick, Jake Johnson, and Ron Livingston, Wilde says she went a little overboard with her character research.

Olivia Wilde Was Drunk On Set Of ‘Drinking Buddies’

Wilde admits that she was drunk for the entire shooting of the movie. “We were hammered the entire movie because it was real beer, because beer on that set was cheaper than water, because we were shooting in a brewery,” Wilde told People.

Wilde recalled that Kendrick was surprised when she got to the set to find out that everyone was drinking while filming was occurring. “She sat down to do the first scene and took a huge gulp of beer, not realizing it was real, and was like instantly hammered,” Wilde said. “She was like, ‘What’s happening? What are you guys doing?’ and we were like, ‘Oh, we forgot to tell you – the beer’s all real and everyone’s drunk. It’s 10 a.m., welcome to Drinking Buddies.’”

Kendrick also has copped to problems drinking on set. “During a scene at the bar, they gave me fake beer, but then during a scene where I’m playing cards with Jake, they gave me real beer, and I didn’t realize it! And so every time I lost, I was pounding beer, and I didn’t realize it was real until halfway through the take,” Kendrick said in an interview with Vulture.

Drinking Buddies is currently streaming on Netflix for your drinking pleasure.
