If it weren't for the gimmicks (and the sadism is so gratuitous it could be nothing else), then the film could easily pass for a minor caper thriller of the '60s, all convoluted plot and calculated kookiness. But cyphers (both female leads) and question-marks (who'll get the money, who'll survive - who cares?) dominate the script as every labyrinthine twist becomes more plodding.

What are critics saying?
Though Duke’s film lacks the warmth and humanism of Something Wild, it’s possessed of a similarly idiosyncratic edginess.
Washington Post by Gary Arnold
Before it takes an appalling turn for the vicious, The Silent Partner seems an uncommonly clever and gripping suspense thriller. Even after the story threatens to self-destruct, you fight the impulse to suffer a major letdown, for the sake of the swell nerve-racking time you've been having up to that point.

An undervalued 1978 thriller with an ingenious script by Curtis Hanson. [23 Feb 2001, p.18]
The New York Times by Janet Maslin
A dense, quirky, uncommonly interesting movie, this time with a high quotient of suspense.
A small but wonderful gem of a thriller: A film in which complicated people and a very complicated plot come together in a mechanism that leaves us marveling at its ingenuity.
