Yeah, I had a similar problem with my games when I was running two games at the same time for different groups- there were a few people (most notably the future missus) who got a drek load of extra karma, nuyen, and contacts, as well as the experience, and before long, she was rivalling the runners who had made thier characters years before, just because her character got to play twice as often.
I don't really know many movies that have a magic theme that work for Shadowrun movies- magic movies tend to be a little more mystical, rather than down and dirty. And I know that's what makes Shadowrun unique, but it's something they're trying to do with Constantine, Dresden Files, or even the new show with Jeff Goldblum.
