The National Post reports in its Saturday, Aug. 12, edition that audiences have returned to new blockbuster movies, but are behaving badly. The Post's Joseph Brean writes that bad behaviour in movie theatres is everywhere these days. This summer there was a brawl at a Little Mermaid screening in Florida and a similar ruckus in France at Creed III. In Brazil, a woman who yelled about a child using a phone during a Barbie screening got punched by another woman, and fought back until a manager separated them. Misbehaviour, however, as simple as scrolling on a phone or posting on social media during the movie also appears to be taking off. Fighting in theatres makes for such viral social media content that it starts to look like a trend, promoted if not actually encouraged by technology. Now, theatre staff are stuck having to smooth over bad experiences with refunds. Some have enacted a "one-warning" policy before kicking people out. Cineplex forbids "using any unauthorized recording or communication device," but has no such ban on scrolling through your phone with the screen lit up. Plenty of things are explicitly banned: displaying weapons, smoking, using a hover board. However, not live-tweeting a movie.
