Christian Bale drastically lost approximately 120 pounds for portraying Trevor Reznik, a factory worker struggling with insomnia. His emaciated physique added an eerie and authentic touch to each scene, demonstrating his dedication to the character.

In a remarkable turn, Bale’s portrayal went beyond mere physique – it convincingly embodied Reznik’s growing paranoia and mental deterioration. His emaciated look and powerful acting turned ‘The Machinist’ into an edge-of-your-seat psychological drama.

In addition to his acting training, De Niro took up boxing to accurately depict LaMotta’s prime. He even participated in actual fights, demonstrating his commitment to both physicality and craftsmanship. This dual dedication turned ‘Raging Bull’ into a cinematic masterpiece of storytelling.

Natalie Portman in ‘Black Swan’ (2010)

For the role of ‘Black Swan’, Natalie Portman spent an entire year perfecting her ballet skills. She shed approximately 20 pounds in the process and mastered intricate ballet movements, resulting in a mesmerizing portrayal of Nina Sayers.
