Is it that movie I was watching on TCM with some teenage boy who had a bird in a massive cage in his room and their was some interspecies love story and tragedy and such? Weird movies are weirder at 5am...
not sure what your movie is, AKS....sounds a little like Birdy with Matthew Modine, but there was no interspecies mingling (though there were sexual overtones)
I had never even heard of that movie until I saw Tarantino praising it in an interview. Tommy Lee Jones' "I'm gonna kill a bunch of people" is a great line.
