Ah, good. History/movies being cleaned up so they give no clue as to the times.
The ending of Peter and the Wolf has been changed. Instead of the hunters dispatching the big bad wolf, he is taken to the Zoo!
It's a venerable practice. The Grimm brothers cleaned up the fairy tales they collected and other folks are doing the same to the stories today. From wikipedia:
"The first volumes were much criticized because, although they were called "Children's Tales", they were not regarded as suitable for children, both for the scholarly information included and the subject matter.
[3] Many changes through the editions – such as turning the wicked mother of the first edition in
Snow White and
Hansel and Gretel (shown in original Grimm stories as Hänsel and Grethel) to a stepmother, were probably made with an eye to such suitability.
Jack Zipes believes that the Grimms made the change in later editions because they "held motherhood sacred".
[4]
They removed sexual references—such as
Rapunzel's innocently asking why her dress was getting tight around her belly, and thus naively revealing to the witch Dame Gothel her pregnancy and the prince's visits—but, in many respects, violence, particularly when punishing villains, become more prevalent.

Who is it that said, "times change and we too change in those times"?
