- Don Adams (Maxwell Smart) appears only in the beginning teaser, as he refused to fully participate in this episode, griping that it was a pale rehash of an earlier segment, and so was replaced by his good friend Bill Dana.
- According to an onscreen super, the episode takes place in August but this does not seem to be possible. It obviously cannot be August 1970 as this has not happened yet. However, if it is August 1969 this would mean that the entire season so far, including all of 99's pregnancy, has happened in the one month since the moon landing referenced in "Pheasant Under Glass". The alternative scenario would be that astronauts landed on the moon sometime earlier in the Get Smart universe than in our own.
- This is the final appearance of Siegfried and Starker in the original series, as well as their lone appearances during the CBS season of Get Smart.
- The Theme of Kaos trying to control weather was repeated in the last orginal "Get Smart" movie "Get Smart, Again!"  staring orginal cast members Don Adams; Barbara Feldon; Robert Karvelas; Dick Gautier; and Bernie Koppell as Seigfried. "Island of the Darned" Kaos Agent Hans Hunter [Harold Gould] guest stars as Koas agent/publisher Nicholas Demente
- The title refers to the 1968 film (and 1963 novel) Ice Station Zebra.
