Blackenstein

Eddie Turner is a Vietnam War veteran who loses both of his arms and both of his legs after he accidentally steps on a land mine, but a brilliant surgeon named Dr. Stein is able to attach new arms and new legs to his body. Unfortunately, Dr. Stein's insanely jealous assistant Malcomb, who has fallen in love with Eddie's fiance Winifred Walker, both spitefully and deliberately switches Eddie's DNA injections, which are necessary for his treatment, with those of another one of Dr. Stein's patients, transforming him in the process into a huge, lumbering and mindless Frankenstein's Monster-like brute.
