What if someone edited Back to the Future II to be more like actual 2015? Not exactly, of course (as with all interpretations of the future, it will, ironically, always be very dated), but just close enough to really feel all too familiar. You could add the Skype or Discord logo to Marty’s video chat with his boss. Replace Jaws 19 with Jurassic World or The Force Awakens (perhaps under the name Star Wars 7). Add some extras who are on their phones. Play some hit song from 2015 when Marty arrives to mirror Power of Love for 1985 and Mr. Sandman for 1955. Maybe one of the McFlies speaks to Siri or Alexa.
