Story is unfolded to a priest while the infamous Baron Frankenstein is awaiting execution for multiple murders he vainly protests have been committed by his manmade monster (Christopher Lee). In the flashback he is seen as a young boy avid for scientific research and sharing with his tutor his determination to build up a human being through chemical hocus-pocus and graveyard snatchings. When their abominable purpose has been achieved, the tutor breaks off the unholy alliance.
Peter Cushing gets every inch of drama from the leading role, making almost believable the ambitious urge and diabolical accomplishment. Melvyn Hayes as the child skilfully conveys the ruthless self-possession of the embyro man.
