The 37-year-old actor had to strip off for the science fiction film and quipped he had to mentally prepare for the scenes.
He shared: "It's a really deep mental preparation needed to show your butt on camera. I'm naked for some parts of this movie."
Chris and co-star Jennifer Lawrence never met before they started filming the movie but are glad the chemistry between them was there when they arrived on set.
Jennifer said: "We didn't. It was a real role of the dice. It could have been a total disaster."
Whilst Chris added: "Yeah, it could have been a total nightmare. We dodged a bullet."
And Chris and Jennifer, 26, had to work closely throughout filming, sometimes stretching to 17 hour days.
He told Entertainment Tonight: "It was an amazing experience, and it's just the two of us, almost through the whole movie. It was really long hours but we had a good time. We spent a lot of time just laughing and bonding over our mutual interests, mostly the movie 'Dumb and Dumber'.
"It's crazy cause you get thrown into a situation where you spend 16 hours, 17 hours a day with somebody. You realise you spend more time, in the course of four months, with this new person than you may with somebody you've known your whole life."
Meanwhile, Chris previously revealed Jennifer embarrassed him on the set of 'Passengers' by letting out a "high pitched" scream and blaming it on him.
He said: "We were sitting in our chairs waiting for the next shot and a big set light bulb exploded nearby and she screamed. High pitched. Very feminine. Then she immediately looked over at me and said, 'Jesus Chris! You scream like a woman! Did everyone just hear Chris?' and for the rest of the shoot I couldn't convince anyone it wasn't me. I just had to own it."
