Honestly Ricky I'm not sure what your getting at with that Diehard scene, yeah its a smartly done little introduction of a characters motivation but again do you need to know someones motivation at all times? cannot it be hinted at but only revealed as a film progresses? Equally its not really a scene that pushes the actor very hard is it? more mild annoyance at the situation. I don't see it as a weakness for a film to leave a significant part to its actors performance, not doing so tends to leave things feeling rather overwritten and unrealistic to me. Again I do kind of see Angel Heart as a bit of a parallel to Scott's original Alien, just with a supernatural rather than sci fi bent to it. Both Brit directors with a strong visual ability they put to extensive use building up atmopshere, both with abnormally strong casts for a horror film who give excellent performances, both take along time before much starts to happen in them, etc.
