CostarEdit
A costar is an actor who shares top billing with a lead in a film, television program, or stage production, and who typically occupies a significant but secondary role. The term captures a practical distinction in casting and marketing: the costar contributes meaningfully to the story and to audience appeal, but the promotion and balance of screen time are centered on the lead. In practice, the lines between lead, supporting, and costar can blur, especially in ensemble casts, limited-series formats, or projects that emphasize star power across multiple episodes.
The concept has deep roots in the history of performance industries and has evolved with shifts in audience expectations, distribution models, and labor arrangements. In classic studio-era cinema, costars often operated within tightly scripted hierarchies and firm contract structures. Today, in television and streaming, the status of a costar can be more fluid, with actors transitioning from recurring roles to costar to lead as a project develops or as a performer becomes more prominent in the public eye. The bargaining dynamics surrounding costars are influenced by unions and guilds such as SAG-AFTRA, which set minimums and protect working conditions for performers at various levels of billing.
