This is a slam-bang chiller about flying foxes , full of scares and lots of blood and gore . It delivers the goods with suspense , tension and hair-raising chills ; plus , the astonishing special effects of this nature , as the ferocious bats seem alive . It's an eerily effective thriller , quite entertaining , though many will undoubtedly find repulsive when the bats attack and eat their victims . The tale can't bear such close scrutiny , but while this thrills ride is going, you won't mind . With a final budget of 5.25 million, the film went on to gross well over 30 million worldwide in theatrical , DVD , Digital and Television sales . Although considered somewhat unsuccessful at the time, the film recouped its entire budget during its first week of release . The vampire bats are splendidly made by means of Animatronics in charge of Robert Zurtzman , Greg Nicotero and Howard Berger . The bats in the film were a combination of Animatronics, CGI , and 2 live bats. The 2 original bats in the film were brought over from Indonesia . The acting is uneven , an attractive Dina Meyer , Lou Diamond Phillips as the patrolman who along with the scientific facing off the creepy bats and killing them in their caves . Bob Gunton is an oddball baddie acting as a mad doctor and the comic relief in charge of Leon .
Interesting screenplay by John Logan , today writer for blockbusters (Aviator , Last Samurai , Star Trek : nemesis , Time machine) . Produced in just under 6 months , the picture continues to hold one of the top spots for fastest produced 35mm feature films to receive a wide-release . The motion picture was well directed by Louis Morneau , in his best movie . He's a B series director, with no much success (Hitcher 2 , Retroactive , Quake , Soldier Boyz , Carnosaur 2). With similar premise , ten years earlier (79) was shot the movie titled ¨Nightwing¨¨ directed by Arthur Hiller with Nick Mancuso , David Warner and Kathryn Harrold , but it was a flop, this one is a superior film .
