Cher Joined Mamma Mia Late-here's Why It Actually Matters
Cher in Mamma Mia
Cher played Ruby Sheridan, Donna Sheridan's estranged mother, in Mamma Mia! Here We Go Again (2018), the sequel to the 2008 ABBA musical film. Her role is a late-film reveal, but it became one of the movie's biggest talking points because the character ties directly into Donna's backstory and gives Cher two showcase performances, including "Fernando" and "Super Trouper."
Why her role mattered
The casting worked on two levels: it added star power, and it gave the sequel a way to deepen the family story without changing the feel-good tone of the franchise. Cher's character arrives as Ruby Sheridan in the present-day storyline, while the film also uses flashbacks to expand Donna's younger years, creating a multi-generational structure that audiences immediately understood. The result was less of a cameo in the traditional sense and more of a strategic late-arriving supporting role.
Character details
Ruby Sheridan is portrayed as glamorous, distant, and emotionally complicated, which fits the film's playful but sentimental approach to family conflict. In the story, Ruby's arrival helps explain Donna's personality and the emotional distance within the Sheridan family, while also allowing the sequel to give Cher a musical entrance that feels like an event. For many viewers, the character's big-screen presence was memorable precisely because it was brief, stylized, and designed to land with maximum impact.
- Character name: Ruby Sheridan.
- Relationship: Donna Sheridan's mother and Sophie's grandmother.
- Film: Mamma Mia! Here We Go Again (2018).
- Function in the story: Adds a family-history reveal and a surprise emotional payoff.
- Signature songs: "Fernando" and "Super Trouper."
Cast context
Cher joined an ensemble that already included Meryl Streep, Amanda Seyfried, Christine Baranski, Julie Walters, Colin Firth, Pierce Brosnan, and Stellan Skarsgård, so her appearance was positioned as a major event rather than a routine supporting credit. The production also used younger counterparts for the flashback timeline, with Lily James playing young Donna, which made Ruby's entrance feel like part of a larger intergenerational puzzle. In marketing terms, the film sold Cher as both a surprise and a payoff, and that combination helped fuel audience conversation before release.

Release and reaction
The sequel was released in July 2018, and Cher's involvement was heavily promoted after her casting became public in 2017. Trailer appearances and stills created unusually strong anticipation for a supporting character, because fans were eager to see how the film would integrate a performer of her stature into an already crowded cast. The response was mixed in the sense that some viewers loved the spectacle while others felt the role arrived almost too late, but the overall effect was unquestionably attention-grabbing.
"How can we resist her!" became the kind of reaction the film's marketing seemed to expect, because Cher's presence turned a familiar sequel into a pop-culture event.
Story significance
Ruby Sheridan is important because she reframes Donna's life as part of a bigger family history, not just a romantic backstory on a Greek island. The film uses her to add tension, humor, and a final emotional flourish, while also giving Cher a platform for classic ABBA material that audiences already loved. That combination explains why her role drew so much debate: it was small in screen time, but huge in promotional value and fan interest.
- Reveal Ruby Sheridan as Donna's mother.
- Use Cher's arrival as a late emotional turn.
- Stage musical numbers that feel celebratory rather than incidental.
- Connect the sequel to the original film's legacy through family history.
