According to The Hollywood Reporter John Hlavin, one of the chief writers on hit US crime series The Shield, has been hired to script the fourth Underworld movie. Len Wiseman, who directed the first two films in the vampire vs werewolf saga, continues as producer. No director or stars are currently attached, though it would be unlikely that Kate Beckinsale would return.
The third film got around Beckinsale‘s absence by being a prequel. That won’t be the case this time, says Hlavin: “I can tell you it's not a prequel. It will satisfy old fans and excite new audiences, meaning that we don't want to redo the first three movies, so steps are being taken to honour what fans have loved but at the same time introduce fresh elements."
