Haley Joel Osment was attacked by the pig during filming.
The lion had numerous trainers and handlers, but no one thought the pig might be a menace.

Although Jasmine the Lion is frequently said to be old and weary, Taureg,
who played Jasmine, was a young lioness, less than two years old (lions in captivity can live up to 20-22 years).

Haley Joel Osment went through puberty during filming.
As the film progresses, you can hear his voice getting deeper, especially at the end.
