I just saw an ad for Michael Moore's Fahrenheit 9/11 which began, "Fahrenheit: the temperature in the atmosphere when it reaches the boiling point."
Um, no. Fahrenheit is a system of measuring temperature, named after the person who devised it. The atmosphere, at least on Earth, is always well above its boiling point (the temperature at which a liquid becomes gaseous). Earth's atmosphere comprises primarily nitrogen (boiling point: -320° Fahrenheit) and oxygen (boiling point: -297.4° Fahrenheit).
With a blatant inaccuracy like that being used to advertise it, I'm not filled with high hopes about the veracity of the film itself.
