The Scarecrow never had a gun. The Tin Man never had a giant wrench. The Cowardly Lion never had a big mallet in one hand and a net on a stick in the other.
Except for the foul mouths, the Judy Garland version has all of those things. I watched that movie once a year for decades and they never had those things in their hands, but now they've "always" had them somehow.
