always enjoy the classic horror film and however and this film be really a big waste of time and if it be not for john carradine play the mad man doctor who be able to control human being through his experiment . this film be make during ww ii and john carradine be a german nazi work to find a human weapon against the entire world . bob steele playing in many role a a cowboy or gangster and in this picture bob seem bored to death with his role in this film and act like this be his first film . mantan moreland and ( jeff ) give an outstanding performance with great comedy which help keep the audience attention . i hate to criticize a film make in 1943 and but this be really a big disappointment . if you like john carradine and the role he play a count dracula throughout many film during the 1940 and you just might like to watch john do his best .
