Did You Know?


The voice of Thor, the Asgard, was provided by Michael Shanks, the actor of Dr. Daniel Jackson. See more »


When SG-1 is getting ready to depart at the beginning of the episode, a M.A.L.P. is seen on the ramp in front of the Stargate while it is dialing. Because of the actual process of establishing a stable wormhole to another gate, an unstable vortex is first formed and "shoots" from the gate for a second. This M.A.L.P. would have been vaporized by the unstable wormhole as other people/equipment have been lost to this as well. See more »


Thor: This is your prison. Your technology will not function here. There are no luxuries, no worshipers, no slaves to do your bidding.
Jack O'Neill: Teal'c, I think we just got the answering machine.
Thor: Only basic sustenance, and time.
Jack O'Neill: Yeah, well, great. Thanks - thanks for the chat.

Before Ra ever took over the body of Jaye Davidson, the Unas were the original Goa'Uld hosts- Creatures both Intelligent, and in this episode, malicious and evil.

While the Goa'Uld were out masquerading as less than beneficent gods, another race was also pretending- to be the Norse gods. This yet unnamed race- assumed to be called "The Asgard" had set up a planet "Cimmeria" that was protected by Thor's very own hammer.

Daniel Jackson's book-worming's have shown him the way to where he thinks Thor's Hammer is situated... But it is not the kind of weapon SG-1 thinks it is. Through a slight misadventure, Jack is trapped with Teal'c- and there are no Doughnut's in sight.

This first Unas played by the 6'8" Vincent Hammond was the very best Unas ever. In fact, the same actor plays another huger Unas, in a season 5 episode, "Beast of Burden". But those Unas' were nowhere near as cool as this original one. Especially with our own Darth Vader voicing him.

This is our first glimpse of Thor as well, and... Well, first impressions are deceiving. Especially if they are a Hologram. A hologram voiced by Michael Shanks. And a glimpse of Galyn Görg as a former Host does not hurt this episode much.
