The story of Nobel Prize winner Marie Curie and her extraordinary scientific discoveries—through the prism of her marriage to husband Pierre—and the seismic and transformative effects their discovery of radium had on the 20th century.

'Radioactive' offers a mixed portrayal of Marie Curie's life, with praise for Rosamund Pike's performance and the film's depiction of Curie's determination. However, criticisms arise over historical inaccuracies, artistic liberties, and insufficient focus on her scientific work. The inclusion of unrelated events and the film's pacing receive mixed feedback, making it an engaging yet flawed biographical account.
