Part of what makes Maggie and Frankie, as well as Scrap (Morgan Freeman, using his famous voice to narrate the film) such compelling characters is their humility and realism. All three of them looked and moved as if they were knocked down, keeping a small kernel of optimism in Maggie’s career potential. They essentially look like real people, in a way that’s become increasingly uncommon (and therefore refreshing) for Hollywood.
There’s nothing glamorous about Maggie, who randomly shows up at Frankie’s gym in Los Angeles one afternoon. All we know about her is that she is a waitress, that she is somewhat distant from her family, and that shows that the family is sinking into poverty. So her quest seems desperate, a one-in-a-million attempt to escape the life that has been orchestrated for her. Frankie refuses to train her, but Scrap convinces him otherwise.
Hilary Swank has a lot to share with her character, playing another young woman from poverty pursuing her dreams in LA. According to Achievement.org, she stood out as an athlete and actress from a young age, her mother Judy strongly believed in her abilities. The two moved to LA when Hilary turned 16, living briefly in Judy’s car while she looked for work. The last acting opportunity arose in the early ’90s, but Swank never forgot her humble upbringing, her main connection to Maggie. As she said in her Oscar-winning speech for “Million Dollar Baby,” “I’m just a girl from the trailer park with a dream.”
