* ActingForTwo: Sam's voice actress Creator/JenniferHale also voices several other characters including [[AlphaBitch Mandy]], leading to plenty of instances of TalkingToHerself.
* ChannelHop: Started off on [[Creator/{{Freeform}} ABC Family]] for its first season, then showed up out of the blue on Creator/CartoonNetwork for the rest of the series; this may have been because Creator/SabanEntertainment co-produced season 1 before Disney bought them out.
* CompletelyDifferentTitle:
** In Chinese, we have ''间谍少女组'' (lit. ''Spy Girl Group'').
* DuelingShows: Started around the same time ''WesternAnimation/KimPossible'' did.
* FakeAmerican: [[Creator/JenniferHale Sam and Mandy's voice actor]] and Alex's second voice actor are both Canadian, though it's downplayed for the former this show came out when she already moved to the US.
* FakeBrit: Jerry's [[Creator/JessHarnell first voice actor]].
%%* InternationalCoproduction
* NamesTheSame: Go ahead, ignore Jerry's middle name.
* NoExportForYou:
** So far, TheMovie doesn't seem to have aired in Canada; nor do they get the first season anymore, only the ''Undercover'' seasons.
** Rectified a bit when the fifth season and movie finally aired on Cartoon Network in the USA in the spring of 2010. Still seems to be scarcely appearing in other territories, though.
** The first 3 seasons are on iTunes, as of January 2017. Anything past that is anyone's guess as to if it'll be put on there.
** Thankfully, the series (and TheMovie) are being released for free on [[https://www.youtube.com/channel/UCeuCusk31pZdvI8ap69A2DA YouTube]]. The full series isn't up as of December of 2017, but they are getting there.
* TheOtherDarrin:
** To put it simply, the English dub switched from American voice actors in the first two seasons to Canadian for the rest of the dub. Clover and Sam's original actresses were retained for the entire series, though, and WordOfGod has said that they wanted to retain Alex's voice as well.
** Latin America replaced all the actors. The Spanish dub changed countries from Mexico to Venezuela, while Brazilian Portuguese moved from São Paulo to Rio de Janeiro.
* TalkingToHerself:
** Both Sam and Mandy are voiced by Jennifer Hale.
*** Mandy's lackeys are voiced by the same women who voiced Clover and Alex as well.
** In the French version, it's Alex and Mandy who share the same voice actress.
