there is a movie called Fitzcarraldo that i would recommend to you. it is on dvd but might be a little harder to find, as i think it was more recently released as part of the Werner Herzog/Klaus Kinski boxset, but i might be wrong. there are a few depressive themes but overall i find it to be awe-inspiring. i do think you would like it. not horror.
The Castle of Cagliostro is one of the most excellent non-depressive, non horror Japanese cartoons i've seen and it's on DVD and i think you would be highly amused by it.
