'Embryo' (1976) – Ralph Nelson.

One of the most intriguing facets to largely forgotten 70s Sci-shocker 'Embryo' is the casting. Rumpled icon, Rock Hudson, squirrelly, Diane Ladd, and the dazzlingly exotic, Barbara Carrera suggest lachrymose soap, or chintzy movie-of-the-week melodrama rather more than grimly gestating terror! Another singularity is the lack of archetypal 'Mad Scientist' tropes, and said 'monster' rearing its far from ugly head in the final act is another notable kink in standard creature feature DNA. The benign-ish Dr. Holliston's (Rock Hudson) cavalier usage of an experimental growth hormone on a purloined fetus has dramatic, wholly unforeseen results! Holliston's placental lactogen rapidly transforms this ailing embryo into the captivatingly beauteous, and voraciously inquisitive adult, Victoria (Barbara Carrera).

Domestic life chez Holliston becomes quirky, as twitchy sister-in-law, Barbara Douglas (Diane Ladd) is piqued by the increasingly malign actions of genetically altered Dobermann No. 1, and sleekly sinister, Victoria. Victoria's insatiable hunger to uncover life's mysteries, matched by her greater zeal for unlawful carnal knowledge with warped Svengali /patriarch, Holliston! More Dorian Gray, than Dr. Moreau, as the film's queasier moments are spawned from Victoria's desperate quest for prolonged life! Her accelerated deterioration can only be arrested by gruesomely harvesting the pituitary gland extract from a 5-to-6 month old fetus! The robust performances, maestro, Gil Melle's moody score, and a sordid, hysteria-laden climax all have an undeniable entertainment value, a fact blithely ignored by the film's many detractors.
