Juliet Is the Sun is the seventh episode of Season 3 of The Brady Bunch, and the 56th overall episode of the series. Written by Brad Radnitz and directed by Jack Arnold, it first aired 29 October 1971 on ABC.
Marcia lands the lead role in the school play, but quickly develops an incredibly huge ego and becomes verbally abusive until she is let go.
Marcia lands the lead role of Juliet in her school's production of "Romeo and Juliet" opposite Harold Axelrod's Romeo. Peter and Jan are cast as palace guards, and rehearse their brief roles repeatedly. Marcia had auditioned for the part of the nurse and feels that she is not good enough for the lead female role. She isn't happy about this news as she believes her mother, who is chair of the play committee, influenced the decision, but more importantly that she isn't beautiful and noble as Juliet should be. Once Carol convinces Marcia that she had no influence whatsoever in casting, Marcia's siblings, unknown to Marcia, go on a campaign to make Marcia feel that she is worthy of the role. Their tactic works, a little too well as Marcia not only accepts the role, but becomes a total diva in the process.
Marcia now feels that she is queen of the Brady household, and that she knows what's best for the play to the exclusion of everyone else, even to the point of rewriting Shakespeare's words. Marcia is heartbroken when her behavior results in her dismissal from the play. At the last minute, when the girl cast as Juliet's mother Lady Capulet gets the mumps, a contrite Marcia asks to be given the role and promises she will act in a professional and courteous manner.
