I strongly suggest to watch the extended "One Vision" video and the Making of the video on the second disk if you've never watched it.
It provides a great, and often hysterical, look into the works of Queen and the extended video is just hilarious.
During the documentary, while they're writing the lyrics of the song, listen for Freddie to sing these lyrics..
"One dump, one turd, two tits, John Deacon." he keeps going too. I've never laughed so hard in my life.
