'An American Dream' (1966) stars Stuart Whitman, Eleanor Parker, Janet Leigh, Barry Sullivan, Warren Stevens, Lloyd Nolan, all of whom are asked to give performances they each probably chose to forget.
Based on a story by Norman Mailer, the film is basically a pile of over-the-top '60's melo-trash that appears to contain some of the most inane and shame-faced dialog ever spoken aloud.
Nevertheless, by the end, 'An American Dream' does manage to come into some sort of shape as a surprisingly bleak film noir, albeit an atonal and unlikeable one.
If 'American Dream' had been produced in France using the same script and starring Alain Delon and Marlene Jobert, it likely would have been seen and regarded still so today as a very powerful invocation of noir as only the French could be capable of making.
As is, too much is lost in its own vulgar translation.
