Bad job by a good director
I'll preface this by saying I'm not a Liza Minelli fan.
Having said that,Otto preminger has made many good films over the years,except for this one.
The premise that a sexual psychopath would first "date",then brutally assault a victim is absurd to begin with,and a major stretch in credulity.Why wouldn't he kill her?
After the scene in the junkyard I watched for about 10 minutes more and gave up.
Maybe Preminger owed someone a favour or had an obligation to the studio,but this is not one of his better films.
