The voice-over includes Satie's famous quote, "All my life people have told me, 'Wait 'til you're fifty, you'll see'. I am fifty. I haven't seen a thing". The film takes place in 1910, when Satie was 44 and clearly before he made that remark.
The actor playing Satie, Nicholas Pennell, has a full head of hair. The real Satie was bald, having started losing his hair in his teens. He even wrote an ironic art song about it, "I Am Bald from Birth" (1914).
