[2] Victor & Hugo was Cosgrove Hall's second cel-animated production to be assisted by the Spanish animation studio Alfonso Productions,[3] as well as their last cel-animated project before the collapse of Thames Television (who lost the 1991 ITV regional franchise round to Carlton Television as a result of bidding too low a month after it premiered, and as such, none of its thirty episodes were ever seen more than once in the United Kingdom).
[4] It was also the last Cosgrove Hall show to feature the voices of Brian Trueman and David Jason, and featured guest appearances from many of the company's earlier characters, including Danger Mouse, Count Duckula, Soames and Potson, and even Damson Bunhandler (a pig newscaster from two episodes of Danger Mouse, who started three episodes with reports about the brothers' most recent crimes).
As mentioned above, Victor and Hugo were based on the two five-time villains of Gaston and Pierre from Count Duckula; while Gaston was a tall, thin black stork, and Pierre a stubby, short parakeet, both Victor and Hugo were humans, but they lived in a world populated by anthropomorphic animals (possibly to allow for guest appearances from other, non-human Cosgrove Hall characters).
The taller of the brothers, Victor was also clearly the leader for Naughtiness International; his two most striking characteristics were his fedora hat and his manicured moustache (the latter enabling him to appear suave, and also making him resemble a spiv).
While his intelligence (and English skills) were notably inferior to those of Victor, Hugo was often able to make sense of his brother's spoonerisms - and he would often describe their chosen profession as "criminiminals".
Apart from Thames Video's VHS release of the first, fifth and sixth episodes (which is now almost impossible to find), this show spawned a series of six tie-in books by Jimmy Hibbert, Robin Kingsland and Rod Green, published by HarperCollins Publishers and Boxtree; they featured Cosgrove Hall's short-lived triangular logo on their front covers (which was a reference to Thames Television's final one, introduced in 1990), and entitled "Fu Man's Choo Choo", "The Big Nap", "Out to Lunch", "The Great Golden Turnip Caper", "The Great Train Robbery", and "Where Beagles Dare".
