Instead, the man onscreen is almost unrecognizable: gritty and haunted, a fighter who looks like he's been to hell and back, because in many ways, he has.

In The Cut, in theaters now, Bloom plays a washed-up boxer chasing a second shot at glory. It's a role that pushed him to his limits, both physically and mentally. To disappear into the character, Bloom lost 60 pounds, surviving on little more than cucumbers and tuna. The extreme transformation left him exhausted, vulnerable and at times, almost unrecognizable, even to himself.

The English actor looks much more reminiscent of his Pirates of the Caribbean days right now than the emotionally wrecked boxer audiences meet in film. It's been two years since he put his body through "extensive" trauma for this role, and it's clear that talking about it now, the experience still lingers.

When you take all three of those away - because you don't really sleep when you're that hungry..." he trails off. "I was sleeping a few hours a night. I literally had no mental or physical capacity. I was lying on the floor between takes and then getting up to work."Bloom sheds 60 pounds for The Cut.

The very first scene they filmed required him to be completely bare, physically, standing on a scale. (What happens at the end of the weigh-in will make your jaw drop.)AdvertisementAdvertisementAdvertisementAdvertisementWhen I ask Bloom about that day on set, he credits the cast and crew for making him feel "so safe" because he felt a sense of community. He says that support allowed him to embrace the sheer exposure the moment demanded, even as the physical toll was staggering."I hadn't really drunk water because I was trying to get this really crazy dehydrated [look]. I was really restricting the water, and all of that made it just way harder than I had imagined," he says, remembering a "feeling of vulnerability - and the feeling of starvation" that took place over three days.

To make sure his body could withstand this kind of drastic transformation, Bloom worked with Philip Goglia, a nutritionist who has guided other actors through extreme roles, including Christian Bale. He went down from three meals a day to one."[Goglia] was in lockstep with production to make sure we timed everything out," Bloom says. But even with expert supervision, the process was grueling. "I couldn't get past 162 pounds; I was stuck at this weight. I photographed my scale every morning and sent it to him. Then just before filming, he said, 'I want you to get in a hot bath.'"Bloom details his physical transformation for The Cut.

He had to soak in it, then drink 2 liters of water before going to bed. "I did it - do not do [this] at home - and I dropped 10 pounds overnight. I got down to the weight. It was crazy."AdvertisementAdvertisementAdvertisementAdvertisementThe effects were as shocking as the method. "Your body just lets go after that process. That's how I got that very dry and not-pretty look."The whiplash of rebuildingWhile filming The Cut, Bloom says, he was "not a lot of fun to be around.""I didn't feel very good - angry and hungry," he says. The physical deprivation triggered more than just mood swings: Bloom says he grew paranoid and struggled to quiet his mind. There was practically "no acting involved," he explains, because his shaky mental state mirrored that of his character."The feelings, the emotions, the intrusive thoughts in the mind, the physical exhaustion, the physicality - it all kind of came to fruition," Bloom says.
