These guest appearances placed her in programs that were familiar to television audiences during the years when episodic dramas, crime series and adventure shows were a major part of prime-time viewing. Her television work helped extend her visibility beyond movie theaters and gave her another avenue to reach audiences.

Before entering acting, Weller worked as a model, beginning her career in another part of the entertainment industry. Her life outside performance also included a love of horses, a personal passion that remained meaningful beyond the demands of film and television. That interest offered a dimension to a career defined by screen credits. The combination of modeling, acting and her private interests reflected a life that extended well beyond the roles audiences saw on screen.

Weller’s death comes at a time when classic films continue to find new audiences through television, streaming and home viewing.
