I really wish there was a readily available Blu Ray box of the man's work. They always seem to be accessible via North American YouTube, but still.
How BFI or Criterion has not put this out is beyond me.
Also, as much as I loved 'Summer of Soul' - 'Can't Get Your Out of My Head' was my favorite documentary of the year, if not film, from 2021. Curtis is likely too subversive for mainstream/the Academy. Perhaps this is why his films haven't been released in a proper format. Although I'm sure music licensing is also at play as well.
