The reason behind his swim I won't divulge here, but it makes for some powerful moments. As he swims, his 2 friends go along with him in a guide boat, and they come to shore for breaks, which leads to some great moments in the film. It's not all on the water. But when it is, it's riveting. As a viewer, I felt like I was swimming right there with him at times.
And the swimming scenes show off the wonderful Hudson Valley, and Joseph Fiennes looks like he really...um...took the plunge. That's really him in the water. Kudos to the filmmakers who must've been on the river an awful lot. (And to the camera people!) Hopefully this film finds its audience in other film festivals and in a future release.
