Stargate SG-1: Season 6 [DVD] - Region 2 DVD

One of very few solo spotlights came from Christopher Judge writing his own show, when "The Changeling" saw Teal'c act out a life as a fireman. One reason for being a fan favourite was its cameo from still-alive-after-all Daniel Jackson. There'd be several more through the year, culminating in a finale that tested how much attention you'd been paying to that all-important back-story.

Other kooky cameos included Dean Stockwell in one of the many spotlights on the energy resource n'quadria, Ian Buchanan as one of the devilish Replicators (and hopefully the end of that plotline) and regular spots from John DeLancie, Ronny Cox and Tom McBeath as the Earth-bound series baddies. More pertinently, we also saw Byers from The X-Files (Bruce Harwood) as a scientist involved with the Antarctic Gate. Lest we forget, there are other portals on Earth. Is that an already planned spin-off on the horizon? --Paul Tonks
