My faux-norsk boyfriend loves Hal Hartley's movies, so I've seen few (though they can be a bit difficult to get hold of) His real favourites are The Unbelievable Truth and Amateur and last week we watched an old VHS of Trust, which was awesome. Sparse, theatrical and well, nothing much really happens, one of the comments on its IMDB page is titled "I love it! But why?" which is pretty damn accurate.
