In the 7 November 2020 broadcast, Svengoolie notes that Them! (1954) runs longer than the usual allotted time for the show, so the Sven content will be limited (though he doesn't say the movie itself is edited). The episode that aired two weeks prior faced a similar issue, and Mighty Joe Young (1949) was said to be edited for time and content.
The revamped 2020 airing (recorded remotely due to the coronavirus pandemic) featured the first appearance of the "Sven Manor music room" digital set (joining the previously-established Sven Cave and Sven Manor backdrops). Like the main Sven Manor backdrop, the music room graphic was created by comic book artist Christopher Jones.
The Sven Song in the 2020 version is a parody of "The Band Played On", written by John F. Palmer and Chas. B. Ward.
