Produced by Samuel Arkoff, this is one of those low-budget (albeit tolerably directed) jobs with several different titles (“The Campsite Murders” and “Forest Primeval” to name a couple) and two or three different release dates between 1980 and 1985 (I split the difference and went with ‘83, although the original release date is most likely ‘81, for those who care.) It’s of interest mainly for featuring Darryl Hannah and Rachel Ward (not to mention Joe Pantoliano, from “Memento” and “The Sopranos”) in early roles. The gals play the girlfriends of forest rangers out on a work detail in the woods who run across an unseen, homicidal maniac. There’s a refreshingly low body count, but, given the number of potential victims who have little else to do but run around and whine, maybe the cast should have been reduced by two or three actors. Other than a couple of minor shocks here and there, there’s also a lack of action and suspense. Come to think of it — no gratuitous nudity, no excessive violence — who exactly was this movie made for? The last third, with the survivors paddling down river in a big raft, starts to resemble a tame “Deliverance” (as well as other forest/slasher movies too numerous to name). There are pretty good killer-in-the-woods flicks (“Just Before Dawn”) and there are really bad killer-in-the-woods flicks (“Berserker”), and this one sits somewhere just south of the border. Davis went on to direct big-budget action movies (including “Under Siege” and Harrison Ford’s “The Fugitive”).
