The image shows Wonder Woman staring at a wall of TV screens, which display images of oil tycoon J.R. Ewing from Dallas, commercials for drinks, a woman driving a sports vehicle with the top down, TV color bars and much more imagery from the period of time.
This photo may be an example of something Jenkins mentioned at CinemaCon, saying that the 1980s setting of the film will hold temptations for Diana. "This film set in the '80s, she has to deal with the temptation of our world, and face extraordinary odds". It is possible that the WW84 logo, which seems to indicate that the film will take place specifically in the year 1984, was chosen as a deliberate homage to George Orwell's classic dystopian novel 1984. The character sacrificed his life during the climax of the first "Wonder Woman", which means the script will have a lot of explaining to do in regards to how Trevor is alive in 1984.
Previously director Patty Jenkins revealed the Wonder Woman sequel will be set in the United States. We'd like to think the second image in the first row depicts the invisible plane, but then it wouldn't be visible on the monitor, would it? Since Pine's Steve Trevor died at the end of the 2017 original, one of the mysteries of the sequel will involve his apparent resurrection.
Plot details for the Wonder Woman sequel are now being kept under wraps. We just gotta show you this little bombshell that Patty Jenkins tweeted out this morning.
