I have to say that, as with his previous feature, I was left a little unconvinced, though the performances are undoubtedly very strong and the late Victorian sea-dog dialogue is consistently diverting.
The trouble is that the more this film strives to be dark and delirious, the more it comes across as just a bit silly.
In a recent BBC interview Dafoe described the set up as what happens when two grown men are forced to go and live alone in a building shaped like a phallus off the coast of Nova Scotia for a month. It features a descent into madness that both men appear to have commenced prior to this ill-fated posting on the rock.
Eggers preserves a sense of ambiguity about the situation. Part or indeed all of it could be hallucinatory. There are moments when the characters appear to comprehend that they are living through a metaphor.
Anyway, one big take-out from the movie (or from the above-mentioned interview at least) has been that Willem Dafoe is one of those rare super-talented, yet understated Hollywood actors that would make a fine guest at a dinner party populated with people he didn't already know, in precisely the same way that Joaquin Phoenix wouldn't.
