The name of actor John Carroll is not shown on the original-release, Chapter 1 film credits until it appears on a sixth-page of actor credits; the first page is a full-body image of ZORRO. The second page is split between head-shots of HELEN CHRISTIAN and REED HOWES; the third-fourth-fifth actor credits page features singular shots of DUNCAN RENALDO, NOAH BEERY and RICHARD ALEXANDER. That is followed by an "And" page that lists: John Carroll, Nigel de Brulier, Robert Kortman, Jack Ingram, Roger Williams, Edmund Cobb, Mona Rico, Tom London, Harry Strang and Jerry Frank. None of the role names are listed.
