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 »

Probably the Best Episode So Far
2 April 2017 | by georgesepiclifeSee all my reviews

This is probably my favourite episode of the season so far, because of the significant plot developments, and because of how well the story nails all the characters. First of all, I love the idea of 'Thor' being in a sci-fi show, and it brings a refreshing spin on Norse mythology. I can tell that this is a very important episode, and I am really looking forward to see how this story will develop. I loved how the episode paired O'Neill and Teal'c together, because I think they have great chemistry, and there were some really funny scenes between them. I can say the same thing for Daniel and Carter, who also work well together. It isn't a perfect episode, with the main negative being more of a personal one - I thought the monster was a little stupid looking, and I expected it to be bigger antagonist in upcoming episodes, but it was killed off very quickly which seemed slightly anticlimactic. I also thought that the pacing was a bit off near in the middle, where the story rapidly cuts between Teal'c/O'Neill and Daniel/Carter a bit too much that it was distracting. But all the plot development more than made up for those small nitpicks, and I am especially intrigued with the woman who was able to have her Goa'uld removed safely. I liked how Sha're and Skaara were mentioned again, and how they were linked into the story. Overall, a fine episode and one that continues to a very solid streak of episodes.
