The CGI for the moving bugs was expensive, so part of the episode was rewritten to have the bugs moving mostly underground.
Mitchell says that they are going to watch Starship Troopers (1997) instead of Old School (2003). Starship Troopers is about a future military fighting endless space bugs.
In the dubbed German version, Teal'c's choice of movie is a "classic" ("Old School") , while Mitchell tells them they are going to see "Star Trek" (not Starship Troopers (1997)).
The Chinese-Language conversation near the start is Dr. Jackson joking about how they need to babysit Lt. Colonel Mitchell. Ben Browder who plays Mitchell has frequently commented that he and his occasional SG-1 co-star Claudia Black (Vala) were in fact "babysitted" by the production crew of SG-1 because they were allowed to ad-lib on-camera and act somewhat disorderly off-camera when they co-starred together for four years on Farscape (1999), but none of that was tolerated by the production crew of SG-1. After the joke, Col. Mitchell embarrasses Dr. Jackson by showing that he understood the comment - obviously Dr. Jackson didn't suspect that Mitchell understood Chinese.
One of the Stargate's capabilities (demolecularization) works in a similar manner as the transporters in the Star Trek universe. Richard Woolsey, played by Robert Picardo (who also played the EMH/Doctor on Star Trek: Voyager (1995)), voices his concern about traveling through the Stargate for the first time, specifically about being reassembled incorrectly. This alludes to transporter phobia, from which three characters in the Star Trek universe have suffered--Doctor McCoy from Star Trek (1966), Doctor Pulaski from Star Trek: The Next Generation (1987), and Lt. Reg Barkley from Star Trek: The Next Generation (1987) and Star Trek: Voyager (1995).
