Ashton Kutcher's De-Aging For Netflix's Your Place Or Mine Involved Low-Tech Solutions

In an interview on the U.K. morning show "Lorraine" (via TODAY), Ashton Kutcher revealed that his de-aging process for the opening "Your Place or Mine" segment had to involve some rather simple adjustments: manscaping and exercise. "So here's the crazy thing, before we shot the sequence where I was 20, I was like, 'I didn't have this much chest hair when I was 20, and I'm like, 'I actually need to mow this thing down a little bit and like, clean it up,'" he said. "And I'm doing sit-ups and I'm like, 'God, I used to have abs when I was 20! What happened?'"

At the moment, it's questionable whether or not Kutcher's efforts are paying off. "Your Place or Mine" boasts a 37 percent on Rotten Tomatoes, where the critics are giving the movie -– and its flashback introduction –- mixed reviews.

Anna Menta, of Decider, said, "The opening is the worst scene in the movie... Your Place or Mine missed its one shot to make us care about Peter and Debbie getting together, and as a result, the next 80 minutes they spend apart is a slog." As for Mark Kennedy, of the Associated Press, he offered partial praise for the film and the appearance of Kutcher and Witherspoon: "This Valentine's Day, it hits the spot if you're in the mood for pretty people acting insecure and clueless."

Luckily, Kutcher didn't make any permanent changes to his body in his attempt to look 20 years younger and, as he said on "Lorraine," his mowed-down chest hair is beginning to grow back.
