People who want to see this movie. 1) it is a "continuation" of the wizard of oz so the lion scarecrow and tin man are in charge of Oz, and 2) the ruby slippers are silver because they can't use the red slippers as they are owned by Warner Brothers ( I believe it's them) but the characters are not. So other movie productions can make movies but they can't use the "ruby" slippers legally they have to use another colour.
