Deletion of Sydney James Harcourt

Comment: He does not meet the criteria specified in . The ensemble/understudy roles are not significant. He has not been in multiple productions. If he has a "large fan base"  that has not been established. The article does not show any unique contribution by him. To sum, being in a mega-hit show does not confer notability on minor performers
