The Shield was one of those acclaimed and beloved TV series that had its own audience for sure, but thanks to a spot on cable, didn't exactly blow up into the mainstream the way it might have. But since the show has wrapped, at least, the people behind it have been moving on to even bigger things. John Hlavin, a writer for the series, has signed on to write the screenplay for the fourth Underworld film.

According to THR, Hlavin is pretty much the only person attached at this point. The director of the first two films, Len Wiseman, is so far only on board as a producer, and Kate Beckinsale-- incidentally, the director's wife-- isn't sure what she's doing either. Hlavin promised THR that "it's not a prequel, and added, "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 honor what fans have loved but at the same time introduce fresh elements." Hlavin signing on probably means that things are moving forward on this film at last, so look for more news in the coming weeks.
