Nigel and Marianne Thornberry (voiced by Tim Curry and Jodi Carlisle) travel around the world with their family making wildlife documentaries, with Nigel as narrator and Marianne as the camerawoman. They have three children:
Despite being nominated for a Daytime Emmy Award in 2001, the show has its share of detractors, mostly bothered by main character Eliza's look (pigtails, glasses, freckles, and braces on her big teeth) and her attitude.
Besides the aforementioned telefilm, in 2002 and 2003, Nickelodeon released two cinema films featuring the family: The Wild Thornberrys Movie (subsequently nominated for an Academy Award for Best Song for "Father and Daughter" by Paul Simon) and Rugrats Go Wild (a crossover with the Rugrats), both of which earned around a modest (at best) $40m at the US box office. Jane Goodall has also appeared in an ep, The Trouble With Darwin, as herself.
Minor historical note: In early February 2003, Nickelodeon devoted a week to the five episodes that take place after the movie, which have the Thornberrys in Alaska with a pop guitarist staying over with them (Shane G, played by Christopher Masterson). After the 4th of the 5 eps aired, Nick then aired a promo for the 5th ep Eliza Unplugged to air on Saturday, February 8, however, they ended up airing The Fairly OddParents instead; as of this writing, that ep remains the only one unaired in the US.
