Les Ailes du désir
Director Wim Wenders' film "Wings of Desire" is set in Berlin at the time of the Wall. He opted to make a sequel, desiring to explore Berlin post-reunification, more so than for the sake of having a sequel, though the original ends with "To be continued". Wenders had earlier planned to make a film about the evolved Berlin in 1991, but not with "Wings of Desire" characters, only doing so upon considering that only his angels could observe the moral changes he found problematic.
