For many Americans, Thanksgiving is about food, or family, or football. But for some, it’s also about going to see a film.

Thanksgiving week is a famously high-traffic time for cinemas, and last year broke records, with U.S. cinemas pulling in $420 million in ticket sales across the five-day Thanksgiving holiday period. Those sales amount to roughly 30 million moviegoers.

What's different about this year though, is that the blockbusters viewers are catching are probably rated PG.
