If you notice something just a little bit off about Jennifer Lawrence's performance in the upcoming sci-fi thriller Passengers during her sex scenes with Chris Pratt, there's a good explanation. The Academy Award winning actress didn't go method. Instead, she got really drunk to work her way through them. Why? Because she was extremely nervous.

Jennifer Lawrence will have her first ever sex scenes in the movie Passengers. And she has them with a man whose well-known to be in a healthy relationship with someone who might be a little bit more famous than either one of them. Chris Pratt and Anna Faris have been married since 2009. And that only added to the pressure felt by Lawrence when it came time to get intimate with her co-star on set. She decided that the only way she could get through it was with a little Dutch courage.

Jennifer Lawrence, who won her first Best Actress Oscar for Silver Linings Playbook in 2013, called the entire experience 'bizarre'. And when it came right down to it, she simply hated the thought of kissing a married man. Speaking with THR about the whole experience, she had this to say.

"Everything was done right; nobody did anything wrong. It's just a bizarre experience. It's really weird."

Though she thought consuming some alcohol beforehand would make it all better, she claims that it only made matters worse. Things did not go according to plan. And she probably won't try this method of acting again. She explains.

"It led to more anxiety when I got home because I was like, 'What have I done? I don't know.' He was married, and it was going to be my first time kissing a married man and guilt is the worst feeling in your stomach. I knew it was my job, but I couldn't tell my stomach that. So I called my mom, and I was like, 'Will you just tell me it's okay?' I was just very vulnerable. That was the most vulnerable I've ever been."

Passengers won't arrive in theaters until Christmas 2016. The story is set in the future and centers on Chris Pratt's Jim Preston, a mechanic on a 120-year journey to a distant colonized planet in another galaxy, who becomes the first traveler to experience pod hibernation failure. Having woken up 100 years too soon, he is stranded in the world of an interstellar spaceship with only robots and androids for companionship. A year into his journey, he decides to wake up a fellow passenger, a beautiful journalist named Aurora. They fall in love but must soon deal not only with the revelation of Jim's misjudged act of waking her but a major malfunction of the ship itself.
