Each of the fan's stories includes a Depeche Mode motif from a previous band project: riding a horse and flinging open doors (Indra Amarjargal's segment, mirroring shots in Depeche Mode: Personal Jesus (1989)); underneath the Berlin U-Bahn (Daniel Cassus runs along roughly the same route as seen in Depeche Mode: Everything Counts (1983)); in a car at night in Los Angeles (Elizabeth Dwyer sings "A Pain That I'm Used To" and "But Not Tonight," in a shot similar to much of the video for Depeche Mode: Wrong (2009), shot in downtown LA); "the king" (much of Cristian Flueraru's segment is dedicated to his photography replicating shots from Depeche Mode: Enjoy the Silence (1990)); riding a Vespa (Carine Puzenat's segment, mirroring shots in Depeche Mode: Strangelove (1987)); and bumper cars (Dicken Schrader, Milah Schrader, and Korben Schrader ride these in a brief scene, just as the band does in the video for Depeche Mode: Get the Balance Right! (1983)).
The scene with the fans camped outside the concert venue was a last-minute idea pitched by the fan being interviewed (Daniel Cassus) that the crew decided to carry out after finishing early during one of the days filming in Berlin.
The friend seen singing karaoke with Daniel Cassus is Jenna Rose Robbins (uncredited), who wrote the Depeche Mode memoir "Faithful and Devoted: Confessions of a Music Addict."
Both Daniel Cassus and Jenna Rose Robbins appear in another Depeche Mode film, Depeche Mode und die DDR (2018). Both of them were surprised to learn they were in it, as neither had been told nor signed releases.
