Back to movies not appropriate for children. Back in the 60s & 70s there was a theater in an affluent suburb famous for its Saturday afternoon kiddie matinees. Every kid movie ever made showed there (to prove how low the bar was, they even showed Santa Claus VS the Martians). Parents would slow down in front of the theater, toss their kids out along with money for tickets and popcorn, and speed away.
One weekend they were showing Tales of Beatrix Potter, which my family opted to see as it had excellent reviews. There were signs everywhere: This Is a Ballet Film! There Is NO DIALOGUE! There is classical music and ballet. The box office staff was grilling parents and refusing to sell to children under the age of ten who were not accompanied by a parent before they sold a ticket.
There were still some poor children whose parents must have said, Fine, fine, fine. Roscoe loves ballet.
Fortunately for once, there were enough adults in the audience who demanded that children not scream or throw food. Children were removed by ushers and phone calls made.
And it is a lovely film.
