That's not the 2015 version of Cinderella playing at the theater
It looks like they're watching an older version from the 60s or 70s and the Wilhelm Scream (low pitched version) literally plays at the beginning. What theater in 2015 still played old movies from the 60s and 70s? Not very many that I can think of.
Could they not afford the rights to show the 2015 version of Cinderalla? It just feels weird seeing them watch a very outdated version of the film.
