Actor Will Poulter has opened up about his physical change for the Guardians of the Galaxy Vol. 3, saying he “wouldn’t recommend [it] to anyone.”

In a recent interview with The Independent, the 29-year-old British actor claims that his training and accomplishments were only possible due to Marvel’s financial support.

“It’s difficult talking about it because with Marvel it’s all secret squirrel, but the most important thing is that your mental and physical health has to be number one, and the aesthetic goals have to be secondary, otherwise you end up promoting something that is unhealthy and unrealistic if you don’t have the financial backing of a studio paying for your meals and training. I’m in a very privileged position in that respect, and I wouldn’t recommend anyone do what I did to get ready for that job. I’ve gone through a series of different diets over the last few months. Now I’m in a maintenance phase, which is quite nice. I’m not eating copious amounts of food to bulk, and I’m not cutting. I’m just maintaining my weight. I’ve gone through periods of looking at food and feeling like I can’t face it, and then you blink and the next minute you’re ready to eat furniture because you’re so hungry.”

Poulter said, “I haven’t been able to eat out with friends or have a drink since starting this lifestyle and nutrition change, so my social life has taken a blow.”

Poulter’s depiction of Warlock in the next Guardians feature is the character’s debut appearance on the big screen. Poulter, who is set to have a key part in the film, discussed how he approached the role, while also distancing himself from the idea of method acting.

“When it comes to an actor’s process, whatever that is, so long as it doesn’t infringe on other people’s and you’re being considerate, then fine. But if your process creates an inhospitable environment, then to me you’ve lost sight of what’s important. Method acting shouldn’t be used as an excuse for inappropriate behavior – and it definitely has.”

Fans will have to wait a little longer to see Poulter in the role of Warlock, since the third “Guardians of the Galaxy” film isn’t set to hit cinemas until May 2023.
