How Long a Mile (2014)

Documentary about Donald Campbell's record-breaking achievements on both land and water. In July 1964, Campbell became the fastest man on Earth as he traveled around Lake Eyre at 403.10 mph in the Bluebird CN7. In December of the same year he broke the water speed record reaching 276.33 mph on Lake Dumbleyung in the Bluebird K7. To this day, Campbell remains the only person to ever set both land and water records in the same year and this documentary examines and celebrates his success.
