CALL NOW is the first video made for Midwest Angelica, and it acts as a trailer for the series while also having canonical implications. It sets both the plot premise and the aesthetic premise for the series. Some fans have expressed confusion around the aesthetic of the series, so Iet's clear that up. The year "1999" acts as a future vision from the 1980s, which is when the film "Midwest Angelica" was allegedly created (in-universe). This is all to say that Midwest Angelica takes a "retro-futurism" approach to its aesthetic. That's why the aesthetic matches that of a 1980s horror sci-fi flick; it's because 1999 is supposed to represent a futuristic vision, not reality.
Speaking of 80s science fiction and horror, Midwest Angelica makes a lot of direct references to films and media of that era. The examples in this video include the title sequence from 2001: A Space Odyssey and the storm cloud from Close Encounters of the Third Kind. Also take a look at the original logo for the series; it was inspired by the 1976 film Logan's Run!
The soundtrack was created solely for this video and was inspired by Vangelis and surprisingly, The Weeknd. Take a listen to the track "Every Angel is Terrifying" from The Weeknd's Dawn FM, you may find some similarities in the quotes from the commercial. Maybe that one was a bit too on the nose!
