A decent cast and director but weak material and certainly does not represent any of the leading actors' best work.
The plot has been recounted by other reviewers.
Judging an actors' performance is subjective of course but I thought Quinn's acting self-indulgent and much to one dimensional.
Another reviewer mentioned that this title was not in Maltin's Movie Guide. It is listed in his Classic Movie guide which covers movies prior to 1960. His review books do not contain every film ever made. Typically movies that received scant theatrical release, were released direct to video, or were TV movies. I don't remember an instance where a major studio film with A list actors was not listed.
