Being an actor can be a demanding job. Everyone looks at movie stars and just thinks about their money and glamour, but ignores that their actual work isn’t a piece of cake. Acting requires actors to have incredible amounts of skills and dedication. It requires actors to exactly deliver lines, follow cues, and immerse themselves into a role. It goes far beyond slipping into character to deliver lines or follow cues and wearing some make-up or even a fake mustache.
Many actors took their body transformations to the extreme, those who undertook vast physical and mental efforts to portray their characters in the best they can. Some are willing to go on dieting for months for a role-proper weight loss, some live with an excruciating muscle gain regime that requires six hours a day in the gym. Their hard work paid off. Many of them won prestigious awards for their works.
