7. Hilary Swank — Million Dollar Baby
Swank’s intense training for the role in The Million Dollar Baby led to a serious foot blister that turned into a potentially deadly staph infection. To prepare for the role, she trained six days a week for three months, spending over two hours on boxing and another one to two hours on weights daily. Though she was only supposed to gain 10 pounds of muscle, she almost doubled that with her workouts and strict diet. Her trainer, Grant Roberts, said he was amazed she could even stand after all the boxing.
8. Margot Robbie — Birds of Prey
It’s rare for a spin-off to outshine the original, and Birds of Prey was not an exception. Despite being a pretty bad movie overall, it did feature Margot Robbie, and her portrayal of Harley Quinn was amazing, as always. Robbie nailed Harley’s personality and didn’t shy away from the physical demands. She trained intensely with ballet dancer and trainer Andie Hecker for Suicide Squad and took it up a notch for Birds of Prey, including learning to roller-skate for the role.
