Our friends at Ain't It Cool News have linked to a nice featurette on BSG season four from the Canadian Space Channel and a show called "Hypaspace." IF YOU HAVE NOT SEEN SEASON THREE (i.e., you're waiting for the DVDs like half of my friends), then this has massive spoilers. If you want to be absolutely unsullied by any hints from season four, then you probably want to skip it. Those caveats aside, it's a nice piece and the brief interviews with multiple cast members are fun.
