The Secret Show was a BAFTA-winning, independently-produced animation series made for the BBC, by Collingwood/O'Hare Entertainment. It was about the semi-secret organization U.Z.Z. and their top agents Victor Volt and Anita Knight, dealing with the dastardly machinations of Doctor Doctor's T.H.E.M. syndicate every second Tuesday, as well as saving the planet several times over from other villains such as The Impostors, Reptogators, and Prince Spong of the Floaty Heads. First devised in 2004, it premiered on CBBC in 2006 (in the UK) and on Nicktoons in 2007 (in the US).
Although the series itself is available online if you know where to look, a considerable amount of media related to it is currently unavailable.
Found/Partially Found Media
The Nicktoons American dub (Partially Found)
Paired with "Wedgie Attack" in the second of the double-billed episodes in Nicktoons broadcasts, the episode "Bogie Ball" had every use of the word "bogie" redubbed into "booger" for all voice lines, and the title-card was changed accordingly. Edited portions of it were uploaded by YouTube User TheSecretShow4You from their own camrip, although in very low quality. (It has now been found in good quality from an unedited source via the link below)
Additionally, the episode "The Z-Ray Goggles Of Power" was redubbed to say "ZEE-Ray Goggles" instead of "ZED-Ray Goggles" when aired on Nicktoons.
It is unknown how many additional episodes were redubbed as only 1 TVrip of the 26 Nicktoons double-bills has surfaced - that being Dr. Hypno Returns Again / Secret Sleep, neither of which appear to have been modified - although on Nov 2nd, 2017, master copies were located for two further double bills, and as of the 23rd they have both been uploaded - the episodes in question being Booger Ball / Wedgie Attack,and Flick The Switch / Giant Brain Of Terror, bringing the total tally to 3/26 found.
The Martian Dub of "Super-Vic" (Found)
One of the most famous pieces of lost media from the show, this was exclusive to the Australian release of the Volume 2 DVD - although TV listings suggest it may have briefly aired on Nicktoons. It was a self-satirical in-character commentary on the episode "Super-Vic", showing the main cast supposedly "redubbing the episode into Martian for the benefit of those watching on Mars", seemingly on their first take. Naturally, the "Martian" is nonsense and the redub devolves into everyone arguing over what the Martian language supposedly is, and what actually happened during the episode's events. Remaining elusive for many years, it was found and uploaded onto Google Drive and shared on Tumblr in its entirety in late 2016.
