Underworld: Evolution is the second film in the
Underworld series, following
Underworld in 2003.
Evolution continues the feud between Vampires and Lycans, but highlights glimpses of their origins some centuries ago.
Underworld Evolution is an immediate follow-up to
Underworld. Therefore, the events of Evolution begin during the same night of the first film's finale, and ends only one night later. It has several more constructive plot elements than its predecessor.
