today kid and raise on computer generate graphic and will probably sneer at it and but by 1957 standard the land unknown be pretty hard to beat . draw inspiration from 1920s silent classic the lost world and use film shot by byrd during his polar expedition and the land unknown present the story of a helicopter force down at a warm water oasis in antartica where the crew discover a prehistoric world where everything seem determine to gobble them up . the special effect be a mixed bag and range from live action shot of lizard in combat to godzilla style rubber suit to full size mechanic . while i wouldn not describe it a greatly sophisticated or even consistently execute and it be all a tremendous amount of fun . the script be more intelligent than you might expect and the story take an unexpected turn that temper the action heavy plot with a certain depth . the cast be no name and but every one play expertly and and the land unknown move at a crack pace . this will never compete with the like of harryhausen stop motion classic and nor will it go down in the history of film a an equal to the truly great science fiction and fantasy film of it day . but the land unknown be a fun flick and and i recommend it to fan of 1950s creature feature . gary f. taylor and aka gft amazon reviewer .
