Benedict Cumberbatch has labelled his need to eat beyond his appetite for Marvel’s Doctor Strange film as "horrific".
The London-born actor, 49, known for playing the spell-casting superhero, stated he could have fed a family "with the amount of eating" he did.
He criticised the film industry for being "grossly wasteful" regarding such practices.
Speaking on the podcast Ruthie’s Table 4, he said: “You have someone who can prescribe you what you’re eating and they can cook for you.
“We had a fantastic chef on the last Doctor Strange film … but it’s this amazing facility to go, ‘Right he needs to be on this many calories a day.
“He needs to have five meals, he needs to have a couple of boiled eggs between those five meals or some kind of high protein snack, cheese and crackers or almond butter and crackers. Crackers. Lots of crackers.’
“For me the exercise is great and the end result is that you feel strong and you feel confident. You hold yourself better, you have stamina through the exercise and the food that makes you last through the gig.
“But it is horrific. I don’t like it personally, I think it’s horrific, eating beyond your appetite … It’s just like, what am I doing? I could feed a family with the amount I’m eating.
“It just slowly, slowly, you have to meet people where they are on these issues in filmmaking. But it’s a grossly wasteful industry.
“So let me think about set builds that aren’t recycled. Think about transport, think about food, think about housing, but also light and energy.
“The amount of wattage you need to sort of create daylight and consistent light in a studio environment. It’s a lot of energy.
“So the first people to stick their head above the parapet to talk about anything to do with climate and excessive use of things, or hypocrisy, or systems that don’t work, get slammed if they’re actors, because they’re ferried about.”
He added: “It is a systemic thing. But as a producer, I’m really hot on that.
“I try to push the green initiative, the green handshake into every agreement I can.”
Cumberbatch is also known for playing Sherlock Holmes in the eponymous award-winning BBC series and won a Bafta TV award for the drama Patrick Melrose, which was based on a series of semi-autobiographical novels by Edward St Aubyn.
