Nathan Juran, director of The Seventh Voyage of Sinbad, tries to make the magic happen again on a much more attenuated budget in Jack the Giant Killer. Torin Thatcher, another Sinbad alumnus, plays a wicked wizard who kidnaps toothsome-princess Judi Meredith. Kerwin Mathews, still another veteran of Sinbad, plays Jack, who rescues Meredith and promises to escort her to safety. Stop-motion animator Jim Danforth creates several fire-breathing perils along the same lines as Ray Harryhausen's special effects in Sinbad; happily, Danforth emulates the Harryhausen style without stooping to imitation. Prominent among the supporting actors is Don Beddoe as an impish genie. In the recently reissued prints of Jack the Giant Killer, most of the original voices have been dubbed over, and incongruous musical numbers added. ~ Hal Erickson, Rovi
