Acting for Two: Tim Curry not only voices Nigel Thornberry, but also his father Col. Ratcliff.
Adored by the Network: Despite being moderately popular at best when it first aired, Nickelodeon pushed it as one of their most valuable commodities, airing it any time they could and even greenlighting two theatrical movies, both of which underperformed.
Bad Export for You: The DVD for the movie has no hardcoded subtitles for when the natives are speaking, so if viewers want to understand what they're saying they have to turn the subtitle track on.
Screwed by the Network: The series had a two-episode grand finale, but the second part wasn't aired until over a year after the first one. When they did air the actual last episode, it was without much advertisement and most viewers weren't aware of it.
Unintentional Period Piece: For the most part, the show is pretty good about not letting on to the exact era it's in. However, Debbie's taste in fashion practically screams "the 90s" most of the time. Doesn't help that her standard outfit is a green, loose fitting flannel jacket combined with torn, faded blue jeans.
What Could Have Been: Originally, the show was be more along the lines of an "educational show" centering around Nigel traveling around the world and teaching people about the various animals that lived there. Nickelodeon decided to change it into a Doctor Dolittle-esque adventure, feeling it would be more successful with a child protagonist.
