Directed by Ari Aster, the film will also feature Amy Ryan, Kylie Rogers, and Broadway stars Nathan Lane and Patti LuPone. TheImageDirect.com Joaquin Phoenix Hopes Son River Will Be Vegan but Won't 'Force' Anything: 'I'll Support Him' The weight gain for the vegan actor comes just a few years after Phoenix went through extreme weight loss for another role. For the 2019 box office hit Joker, the actor agreed to lose 52 lbs. at the urging of director Todd Phillips, who thought his character, Arthur Fleck, should be "real thin." At the time, Phoenix lost the weight carefully and under the guidance of a doctor, but the strict calorie deprivation he endured continued to affect his eating habits after he hit his goal. "Once you reach the target weight, everything changes," he told the Associated Press. "Like so much of what's difficult is waking up every day and being obsessed over like 0.3 pounds. Right? And you really develop like a disorder. I mean, it's wild." Though he struggled mentally with the weight loss, the actor found that he felt better physically than expected. "I think the interesting thing for me is what I had expected and anticipated with the weight loss was these feelings of dissatisfaction, hunger, a certain kind of vulnerability and a weakness," he said. "But what I didn't anticipate was this feeling of kind of fluidity that I felt physically."

"And I think that really lent itself to some of the physical movement that started to emerge as an important part of the character." But he emphasized the impact on his mental state. "As it turns out, that impacts your psychology, and you really start to go mad when you lose that much weight in that amount of time," he explained to AP.
