About the film
Celsius 41.11 is a 2004 political documentary film inspired by, and partially in response to Michael Moore's film Fahrenheit 9/11. The title was chosen because, according to the makers of the movie, 41.11 °C is "The Temperature at Which the Brain Begins to Die", which is the film's tag-line.
