You guys should check out the eastern European fanfilm "Start Wreck: In the Pirkinning"
It's kinda the most epic crossover fan film i've seen. Plus for something with oddly translated english subtitles, pretty freaking funny. pretty much the highest quality special effects for something like this I've ever seen too.
It's a B5/Star Trek crossover. There's two versions, the latest has replaced all the ships with original designs since they probably got in trouble, but if you check out the previous version it's got all the actual ships from Trek and B5, Epic.
