The actor, 39, stopped by The Ellen DeGeneres Show on Wednesday where he opened up about going nude on screen in Deadpool. Apparently, he really has no issue with it.
"I'm not above taking my clothes off for money, that's the bottom line," he joked.
In one scene, the actor, who plays the title character, bares it all for a nude fighting scene that shows off more than just his martial arts abilities.
"You have a little talk with the crew at the beginning of the day and say, 'You guys, you're going to see things that you shouldn't see,' and you just kind of go for it," he explained.
And it didn't take Reynolds long to adjust to his new, nudist lifestyle on set.
"I kind of got an idea of what it's like to maybe work in the adult film industry," he said. "It's just sort of like by lunchtime you're just like, 'Greek salad's good isn't it?' and you're totally nude standing there at the line. You lose that sort of filter for a minute there."

But Reynolds said he's had his fill of nudity for a while.
"That broke me," he joked. "This morning I showered in a three-piece suit."
The actor also admitted he was extra careful to follow the choreography to avoid any accidental injuries – especially while naked.
"You don't want to get hit there," he said wide-eyed. "We shot this in two days, and the entire set was on fire."
But it turns out, the real struggle wasn't acting out a fight scene in a burning building; it was getting the "eight hours" worth of makeup done everyday.
"I get into set around 1 a.m. in the morning and I start this long process of doing head-to =-toe makeup," he explained. "You can't do anything. You stick to everything, so if I fell asleep on the couch and get up, the couch would come with me."
