Life in plastic proved fantastic for Greta Gerwig's Barbie, a movie that highlights the dangers of toxic masculinity without actually putting men down in the process. The film also gave audiences a detailed look into the titular characters' pastel paradise, a seemingly utopian society officially controlled by various Barbies. That said, Barbieland presented a morphed version of reality partially borrowed from Seahaven, the setting of Jim Carrey's philosophical comedy: The Truman Show. Moreover, Robbie's viral Letterboxd list "Watch for Barbie" provided some context clues for fans trying to piece together the film's plot and central themes.
