Sir Arthur Conan Doyle's The Lost World is a 1999 television series loosely based on the 1912 novel by Sir Arthur Conan Doyle and follows a band of British adventurers (Professor Arthur Summerlee, Marguerite Krux, Major Lord John Richard Roxton, Edward T. Malone, and their leader Professor George Challenger) as they try to find a way out of an uncharted plateau of the Amazon rainforest. The group is also assisted by a young jungle-savvy (and scantily-clad) woman named Veronica Layton.
In season 2 episode 17, our heroes are inflicted with a curse that slowly turns them into animals, resulting in Marguerite eating a mouse and trying to eat Ned before turning into a snake, and John seemingly turning into a jaguar or something.
