Jonwo, they're actually not copyrighted, but they are trademarked.
A copyright expires. Trademarks can be renewed indefinitely as long as it can be proven that the trademarked image is essential to the business. As long as Warner Bros. owns the trademarks (dozens of them on MGM's Oz alone), no one will ever be able to use the likenesses of Garland as Dorothy, Hamilton as the Witch, Bolger as the Scarecrow, the ruby slippers, the Emerald City depicted like upside-down green test tubes, etc.
Eventually, the rights to the MGM film will pass into public domain, but if Warners holds the trademarks, nobody will ever be able to sell the film (or aspects of it) without licensing the trademarked images. Good luck with that.
For another example, Mickey Mouse has already passed into public domain for Disney, but they have trademarked his image "for the business."
And what good is a public domain Mickey Mouse if you can't legally use his image?
The trademark can be renewed forever, never expiring.
