Chris Pratt has spoken a little about what it was like filming sex scenes with his Passengers co-star Jennifer Lawrence in a new interview, revealing that he felt that “the responsibility falls on me” to make things as comfortable as possible.

The 37 year old star, who was recently named as the second most valuable box office presence in Forbes’ Best Actor for the Buck list, had to strip down with his co-star for a nude scene in the upcoming sci-fi drama. It’s something that virtually all actors have to do, and it’s rarely without its embarrassments and nerves.

Even though they are great friends, Lawrence had already said in a previous interview that she relied upon a mixture of alcohol and anxiety to get through them, so now it was Pratt’s turn to say how he felt about them.

“I don’t want to make generalizations based on gender, but I feel the responsibility falls on me [to make my co-star comfortable], and I’ve been in that situation a couple times,” Pratt told The Jess Cagle Interview this week.

“Essentially it’s your job to just minimize the discomfort by, you know, making sure there’s nobody else on set than is required, having a closed set, periodically checking in, and just doing everything you can to assure the person you’re with that they’re okay.”

“For all the sense of anxiety that comes leading up to a scene like this, you get into it and you realize there’s really nothing sexy about it at all. It’s just really awkward. But you know, it’s part of the gig and you just do what you can to check in with the other person and try to minimize any discomfort that they feel.”

Lawrence told Seth Meyers as long ago as last year that there was not that much nervousness ahead of the scenes. She and Pratt didn’t discuss what they would do, and they wouldn’t know where to begin anyway. “‘What do you think, are you gonna hump me once? Are you gonna be on top?’ You don’t talk about it at all!”

Passengers is released on December 21st in the U.S.
