open request for suggestions

Our college anime club is trying to figure out what to show for opening night next semester. It must be a movie or an OAV, to fit in a few hours. Must be good enough to convince an auditorium full of new students to remain in the club.Must not be incredibly depressing, too blatantly pornish, too overly gory, or, alas, too blatantly yaoi. The Utena movie, Spirited Away, Castle of Cagliostro, Laputa, Ghost in the Shell and Hoshi no Koe have all been shown recently, and Grave of the Fireflies, Angel Sanctuary, and Ninja Scroll have all been vetoed as violating the above criteria.

Any suggestions?
