I don't think this film entirely comes off - though, given the talent involved, both in front of, and behind, the camera, there's no way it can be without interest.
Fellow reviewer Trevor Wilsmer has largely spoken my own thoughts on what's right and what's wrong here: I'll just add that this is not one of Dirk Bogarde's better performances, largely due to miscasting. Bogarde has too much senstivity to convince as the parvenu executive who rises, by plotting, to control the steel corporation (closely based on the real German steel firm Krupp's). That said, he's never less than watchable......More happily cast are Bergman favourite Ingrid Thulin as Bogarde's lover/wife and Helmut Berger, making his debut, as her decadent son.
One irritating factor about the film is the dubbing of most of the cast: I think only Bogarde and Berger escape, everyone else is clumsily lip-synched in a very obvious way. It's only a minor distraction, though.
