Reign of Fire is a 2002 post-apocalyptic science fantasy film directed by Rob Bowman and starring Matthew McConaughey, Christian Bale, Izabella Scorupco and Gerard Butler with the screenplay written by Matt Greenberg, Gregg Chabot, and Kevin Peterka.

The film is set in England in the year 2020, eighteen years after a London Underground tunnelling project inadvertently awakened dragons from centuries of slumber and the creatures have subsequently replaced humans as the dominant species on Earth. With the fate of mankind at stake, two surviving parties, led by Quinn Abercromby (Bale) and Denton Van Zan (McConaughey), find that they must work together to hunt down and destroy the beasts in a desperate attempt to take back the world.

The film was released by Buena Vista Pictures through the Touchstone Pictures label on 12 July 2002. Upon release, it received generally mixed reviews from critics and underperformed at the box office, grossing far less than expected, only $82 million on a $60 million budget.
