The Runaways (2010)

Based on the description provided, here is a two-paragraph summary for "The Runaways (2010)" for the list "Best Biography movies": Joan Jett and Cherie Currie, two rebellious teenagers from Southern California, become the frontwomen for the Runaways -- the now-legendary group that paved the way for future generations of female rockers. Under the Svengalilike influence of impresario Kim Fowley, the band becomes a huge success, and the film charts their explosive rise through the 1970s glam-rock scene. Powered by electrifying performances from Kristen Stewart as the fiercely determined Jett and Dakota Fanning as the vulnerable yet provocative Currie, the movie captures the raw energy, chaotic touring life, and internal fractures that defined the band's short but impactful career. It vividly portrays their journey from ambitious kids to international stars grappling with a world of fame, exploitation, and rock and roll excess. *The Runaways* earns its place among the best biography movies by avoiding the sanitized clichés of the genre and instead embracing the gritty, visceral spirit of its subjects. Rather than attempting a sprawling life story, director Floria Sigismondi smartly focuses on the band's volatile formation and meteoric moment, giving the narrative a potent and immediate feel. The film’s strength lies in its authentic portrayal of the era's music scene and the powerhouse performances that go beyond mere impersonation to capture the raw ambition and emotional turmoil of these young pioneers. It succeeds not just as a chronicle of a band, but as a compelling exploration of female empowerment, the cost of fame, and the revolutionary act of teenage girls demanding a place in the male-dominated world of rock music.
