One of the most memorable — and odd — moments in The Sopranos was the bizarre Livia Soprano CGI who appeared in season 3, which led many viewers to question why showrunner David Chase included the scene. Tragically, actor Nancy Marchand died during the show's run, which led to The Sopranos killing off her character off-screen, leaving Tony (James Gandolfini) distraught. Many characters die in The Sopranos, but the death of Tony Soprano's mother undoubtedly affected him the most. Nancy Marchand was a standout part in the early seasons of The Sopranos making the Livia Soprano CGI moment stand out even more.
Following Nancy Marchand's death, the plans for Livia on The Sopranos changed and the character was killed off. Marchand only appeared onscreen once in CGI. Tony confronts his mother to warn her not to incriminate him to the FBI. The conversation turns into an argument about Livia's refusal to fill out the books his wife Carmela Soprano (Edie Falco) had bought for her 20 years ago — journals designed for her to share her life experiences with her grandkids. Ultimately, Tony Soprano's mother had to be rendered in CGI because their story wasn't over yet.
