Revealing mistake: At the beginning when the one monkey falls to its death, it's obviously a stuffed animal posed as a dead monkey.
Audio problem: When the monkey walks to the cradle to calm the crying baby, in the wide shot the baby is crying out loud, then in the close-up he is totally calm, mouth closed, yet the crying is still heard.
John Clayton: Half of me is the Earl of Greystoke.
John Clayton: The other half is wild.
Trivia: The dialogue of Andie MacDowell (Jane) was dubbed in post-production by Glenn Close.
