At the end of the credits Édith Piaf's "Non, Je Ne Regrette Rien" plays at normal speed, then slows down to the speed it was at the beginning of the film during Hans Zimmer's score and throughout the movie. Then we see the title stop in the center of the screen as the song ends.
There are no opening credits or titles.
The movie title never appears in the beginning of the movie, but appears three times during the end credits. Once at the beginning, again after the main actors and developers, and once more at the very end.
Earl Cameron is credited as "Elderly Bald Man". Ninety-two years old during production, Cameron had nonetheless never lost his hair, and he did not appear to be bald in this film (he's the attendant at the Dreamers' "opium den").
