James Cameron was involved in the production of both of these, and the two share many common themes. A lot of the societal conditions seen in Dark Angel
(bad economy, social unrest, police checkpoints, urban decay) are also present in Strange Days
, and it's easy to believe that the world of the film could've persisted as it was for another decade before the Pulse caused a total economic collapse and made everything even worse. Also, the presence of sensory-recording SQUID technology in 1999 could be seen as a precursor to all the advanced technology of 2019.
