Alternative title captions appear over the opening sequence on some US prints. Instead of "Richard Greene in The Adventures of Robin Hood" they state "Richard Greene plays Robin Hood – Adventures in Sherwood Forest". This practice occurred because of an FCC rule demanding that reruns of a series be retitled for syndication packaging if aired while first-run episodes of the series were still being shown on one of the three major networks. Five years of "Gunsmoke" episodes, for instance, were retitled "Marshall Dillon" for syndicated run because "Gunsmoke" was still going strong on CBS.
