A Failed Attempt...
One would think that Conrad's novels would be perfect material for film, but just about every attempt to adapt his books to movies has been a failure ("Lord Jim" with O'Toole was awful, "The Secret Agent" with Bob Hoskins mediocre, as was the made for TV miniseries "Nostromo"). This effort to commit "Victory" (one of my favorite Conrad novels) to film is no exception.
The main problems (among many) are the flat acting and the poor choice for casting. Half of the casting problem would have been solved by switching the lead roles - casting Sam Neill as Heist and Willem Defoe as Mr. Jones rather than the reverse (Mr. Jones should be gaunt, cadaverous, and sinister looking. Sam Neill is a fine actor but he is none of those things, and is completely out of place in the part).
