The Underworld Franchise is a series of dark fantasy action horror films created by Len Wiseman, Kevin Grevioux, and Danny McBride, that follows characters who are caught up in a war between vampires and werewolves (called “lycans” within the films). Most of the movies star Kate Beckinsale as the protagonist, Selene.

The first film, Underworld, was released in 2003; it introduces Selene, an elite vampire-warrior who defies her orders, and Michael Corvin (Scott Speedman), a human who gets caught up in the war. The second film, Underworld: Evolution (released in 2006) follows Selene and Michael as they are hunted by their enemies.

The third film, Underworld: Rise of the Lycans (2009), is the prequel to the series, chronicling the origins of the vampire-lycan war. The fourth film, Underworld: Awakening (2012) is the sequel to Underworld: Evolution. In this film, humans have discovered the existence of vampires and lycans, and are trying to eradicate both species. A final film, titled Underworld: Blood Wars, was released internationally on November 24, 2016, and in the United States on January 6, 2017.

The Underworld Franchise received generally negative reviews from critics but amassed a strong fan following and grossed a total of $539 million, against a combined budget of $207 million.
