The Fire Inside chronicles the journey of boxer Claressa ‘T-Rex’ Shields from Flint, Michigan, as she trains and becomes the first American woman to achieve an Olympic gold medal in boxing, highlighting her determination and athletic achievements.

The Fire Inside Is Just As Realistic As It Is Inspirational

Beyond the realistic portrayal of Claressa’s life before and after her first Olympic win,The Fire Insideportrays the boxer with depth and humanity. She feels like a real person — imperfect, hard on herself, a self-proclaimed bully, a fighter, and a struggling teenager. So often, biopics are more concerned with idolizing their subjects than delving into who they truly are. Jenkins’ script is the complete opposite of that. Claressa is flawed and that, more than anything, makes us root for her all the more. She doesn’t always make good choices, but she’s still deserving of all her success.

It’s a sports drama that encapsulates the experience of living in Flint and a powerful, character-driven story that isn’t afraid to show the gritty aspects as they actually are.

The film’s pacing is excellent, as it builds up to Claressa’s first win before the adrenaline falls, and we glimpse the hardships that continue.The Fire Insideis inspirational, but it’s also deeper than the run-of-the-mill athlete success stories we’ve become accustomed to. Claressa’s story subverts expectations of what a big sports win looks like. After Claressa won an Olympic medal, I was not emotionally ready for the despair that followed. Morrison structures the film so we’re riding on a high before it’s swiftly taken away. Claressa’s win, for a while after, feels like it was a dream.

The Fire Inside Boasts A Heartwarming Dynamic Between Claressa & Jason

Brian Tyree Henry & Ryan Destiny Are Excellent Together

All of Flint roots for Claressa, butThe Fire Inside’s core relationship is between Henry and Destiny, who first broke out in the seriesStar. In her feature film debut as a lead, Destiny is astonishingly good. She balances Claressa’s emotional spectrum, which ranges from angry to heartbroken, triumphant to frustrated. Claressa refuses to act any differently to gain favor, and Destiny plays that with a fiery spark that underscores her desire to remain true to herself. Not playing the game proves difficult, but just as the film is grounded in realness, Claressa is just as firmly rooted in it.

Claressa finds stability with Jason, who not only trains her but takes her in after her mother, Jackie (Olunike Adeliyi), kicks her out. They are two peas in a pod, and Jason acts as a trainer and father figure to Claressa, believing in her ability to go far. Henry is wonderful as Jason; he’s patient and kind, but also endlessly annoyed with Claressa when she gets a certain way. Henry knows how to balance Jason’s pushy coach sensibilities with fatherly affection. He’s gentle but firm and perfectly complements Destiny’s Claressa. They’re the heart and soul of the film.
