Around 13:28 into the episode, the shot of the opening wormhole of the Stargate is obvious stock footage from the pilot, since the equipment to the sides of the gate are covered with olive tarpaulins. In the shots before and after, these tarpaulins are not there.
Around 19:45, when Teal'c is getting into the space suit you can see two members of the film crew, one of whom is holding what looks like a script.
