Underworld is the principal name under which British electronic music duo Karl Hyde and Rick Smith have recorded since the late 1970s. The band is perhaps best known for two tracks, Underneath The Radar in 1988 and Born Slippy .NUXX, a track made popular in the hit 1996 Danny Boyle film Trainspotting.
Underworld is a 2003 horror/action movie (see 2003 in film) about the secret history of vampire and werewolves, where the latter are referred to as "Lycan" as an abbreviated form of lycanthrope. While the film and its sequel opened to mixed reviews they have developed somewhat of a cult following, as films of their kind are seldom so ambitious. The main plot revolves around Selene (Kate Beckinsale), a female vampire "Death Dealer", or one who hunts Lycans, a job she is extremly good at; due to the fact that she is fueled with hatred for the whole species, whom she belives to be responsible for her family's slaughter.
