The only Goofy Gophers cartoon in which Mel Blanc voices both Mac and Tosh.
The last appearance of the Goofy Gophers and the only cartoon that features the Goofy Gophers and Daffy Duck.
The Russian astronaut in the spacecraft is a play on the Space Race between the United States and the former Soviet Union.
Mac and Tosh were the WB counterpoint to Disney's Chip and Dale. But although both pairs sported names that were a spoof on British words, the gophers were the more sophisticated (and polite) duo.
The soundtrack has an unusual accompanying reed flute accent, which makes for an interesting effect.
