This 1936 work by Sergei Prokofiev is familiar to children throughout the world, and has been recorded dozens of times. There are at least three animation versions, the first being from Disney in 1946.
For my money, the best version of the work is a 2006 stop-motion animation version by Suzie Templeton. In Templeton's telling, there is no narration or dialog, and she is not afraid to darken things up a bit. Still, the ending is positive for Peter and his wolf alter ego.
