The 21st century has seen many great disasters, but possibly none so great as the cinematic Hindenburg which was 2000â€²s Battlefield Earth. Celebrity Scientologist John Travolta produced, promoted and starred in this stinker of a movie, which was based on a book of the same name by the "religion"'s founder, L. Ron Hubbard. The movie depicted a post-apocalyptic future in which Travolta's character led stupid-looking dreadlocked aliens in high-heeled boots to enslave humanity. At the end of the movie, the human resistance, led by Barry Pepper and his collection of cavemen and bad actors, managed to defeat the aliens by shooting them down with the help of thousand-year-old planes in a way that made Independence Day look like Top Gun and Top Gun look like a gritty documentary about fighter combat. It flopped, it was panned, it was trash, and it brought attention to Scientology in exactly the opposite way that its creators had intended. That its financial loss may have been as little is $15 million was surely scant consolation. Definitely a contender for the biggest turkey of all time.
