Psychomania is a low-budget, well-done shocker with a tightly-knit plot and a believable surprise ending.
Lee Philips does a fine acting job as the karate-expert artist from a family with a psychotic background, who gets involved in a pair of bizarre murders. Shepperd Strudwick and James Farentino are believable as the lawyer and tough motorcycle hood respectively.
Richard Hilliard’s realistic direction and Louis McMahon’s excellent camerawork help build the suspense of Robin Miller’s screenplay to a satisfyingly real ending. Some of the dialog shows good imagination.
Probably with a bigger budget, film could have been an excellent psychodrama.
