Ian sez, "The four-episode miniseries Masters of Science Fiction aired last August. The full six-issue series (including the two never-aired episodes) will be released soon on DVD. SFScope is giving away ten copies of the two-DVD set." Holy crap, I had no idea Stephen Hawking was the host of this — awesome!
