Tonya Harding – Margot Robbie
Certain transformations on this list vary in their level of impact. Although Margot Robbie maintains her recognizable appearance in the black comedy "I, Tonya," she remarkably embodies the infamous figure skater Tonya Harding.
In order to portray this role, the Australian actress underwent four months of rigorous training. Consequently, she developed a significantly more muscular physique than her usual appearance. During the process, she even endured a herniated disk due to the intense skating involved. In several scenes, Margot dons either heavy makeup or no makeup at all. She genuinely transforms into Tonya on the screen.
