Do you talk when you're alone?
I do, though not always, but enough to say if I'd awakened to my boat taking on water I would have at least said, "What the HELL?!" And if this movie had starred me... I would have had pages of monologue.
What an odd choice that our sailor Redford says nothing, barely even a groan throughout, except one loud f-bomb. This bothered me more than anything else, even the shaving scene.
Interesting film overall, and a good performance by mute Redford.
