In 2004, the Discovery spin-off network aired Dragons: A Fantasy Made Real — an hour-and-a-half special about the evolution and biology of fire-breathing dragons. The speculative show hinged on the fabricated discovery of a dragon in the Carpathian Mountains. 
Try as you might to avoid the noise, The Last Dragon - a docudrama about paleontology and dragons - screamed out at you. "Do not believe this slice of old hokum," was what it yelled. 
Dragons: A Fantasy Made Real is a film that gives us an imagined scientific hypothesis on dragons.
