The Heat is a 2013 American action comedy directed by Paul Feig and written by Katie Dippold, starring Sandra Bullock and Melissa McCarthy as mismatched law enforcement partners tasked with taking down a Boston drug lord. The film follows uptight FBI agent Sarah Ashburn and foul-mouthed Boston detective Shannon Mullins, whose clashing professional styles complicate their investigation of the elusive mobster Simon Larkin. Released by 20th Century Fox on June 28, 2013, the movie was a major box office success, grossing $229 million worldwide against a $43 million budget, despite receiving mixed-to-positive reviews from critics. The plot is packed with comedic set-pieces and twists, including a shocking reveal that the DEA agent they trust is actually the criminal mastermind Larkin operating undercover. After surviving captures, a car bomb, and a violent attack that leaves Mullins's brother comatose, the duo reconcile, arm themselves, and ultimately defeat the villain in a thrilling climax.
