One of the craziest ones is the fact that the studio believed one of the key ways for an audience to identify with a character was through their eyes, so they wanted Jack to have a giant pair of friendly eyeballs instead of his signature sockets.

Just try getting this Adult mask and putting those giant googly eyes on it.
