Robert Pattinson And Charlie Hunnam Each Dropped 35 Pounds For New Movie

To escape your status as an on-screen heartthrob, it’s most likely best to accept a role in a historical adventure epic shot in the jungles of Colombia, where you’re secluded from all technology and screaming fans. There, apparently, you’ll also be able to drop 30-plus pounds.

That’s exactly what Robert Pattinson and Charlie Hunnam did for their new movie, “The Lost City of Z .” The “Twilight” star and the “Sons of Anarchy” actor went full-on method for their roles in the James Gray–helmed film , which tells the true-life story of British explorer Col. Percival Fawcett (Hunnam), who returns to his beloved Amazon ia time and time again with his aide-de-camp, Cpl. Henry Costin (Pattinson), in an attempt to prove that a secret civilization exists there. The travels culminate in Fawcett’s disappearance, which is still a mystery today.

In order to truly portray these jungle-hungry explorers, Hunnam and Pattinson let their muscled physiques dwindle down, and both lost some 35 pounds.

“I don’t think I was too much fun to be around,” Hunnam told “Good Morning America ” in a taped segment that aired Tuesday. Pattinson, who also grew a beard and wore glasses for the film, added, “The main conversation was us saying like, ‘Did you eat a second egg this morning?’”

Hunnam said that if either of them went off set for a moment, the other would be “suspicious” that he was sneaking a snack. But it was all for the craft!

The actors even made themselves disappear, in a way, by unplugging from the world for months. 

“It’s incredible,” Pattinson laughed, explaining that being disconnected from everything was a nice escape . “’I’m sorry, I have to go for six months and I am deeply in character. Don’t call me.’” 

“I didn’t use email once, I didn’t go on a computer, I didn’t make a phone call for four months. It was so liberating,” Hunnam added. 

“The Lost City of Z” hits limited theaters Friday.
