Sleeping Dogs Lie (2006)
Or my preferred title, Marley and Ooh My. Though the word in the title that will get the most attention given the plot details is dog, it's really lie that is doing the heavy lifting here as this absurdist comedy probes the ethical question of how honest one should be with others, particularly romantic partners, about their sexual history. It seems to partner well with Chasing Amy which comes at the issue from a different angle, and I'd argue a more satisfying one ultimately.
I think 1SO hits on a point that could have stood to be developed more. The film, in part of its absurdity that I found a bit tough to deal with generally, paints Amy's parents as extremely strict, keeping her and her fiancee in different rooms during their visit. I suppose the implication exists that her action could have been a response to the repression, but she never broaches this when dealing with the aftershocks of the revelation to indicate it is the reason. I guess ultimately I didn't find it as funny as I might have hoped, I didn't find the thematic strands to be clearly enough woven, and the acting on the whole was a bit stilted. Unfortunately I don't really see it.
