Disney’s adaptation of Peter Pan is from 1953. It won’t go out of copyright until never. Congress has pushed back the public domain cutoff so many times now that it’s safe to assume that the public domain is dead, a relic of the past. Even if Congress stopped meddling with it, the Disney version of Peter Pan won’t enter the public domain until 2048, because obviously people won’t feel compelled to create anything if their great great great grandchildren can’t directly profit from it.
