Mamma Mia! 3 is the anticipated third installment in the beloved musical film series based on the stage show that features the music of ABBA. The franchise began with Mamma Mia! in 2008 and continued with Mamma Mia! Here We Go Again in 2018, both of which combine romance, comedy, family dynamics, and energetic musical performances.
Unlike those earlier films, Mamma Mia! 3 is still in development rather than already completed. Lead actress Amanda Seyfried — who plays Sophie Sheridan — has publicly confirmed that the project is happening and expressed strong interest in returning to the world of love, sunshine, and ABBA classics. She’s talked about starting production ideally in summer 2026, although this depends on schedules and script readiness, and hasn’t started filming yet.

At the moment, the official plot hasn’t been released by Universal or the filmmakers, so there’s no confirmed story yet. However, interviews and cast discussions give some hints about what fans are expecting and hoping for. Because Sophie’s character has grown older since the second film, many believe the new movie could focus on her life as an adult and possibly explore her experiences with love, family, and maybe even her own children — potentially singing iconic ABBA songs in new ways.
There’s also buzz about the return of original cast members. Actor Stellan Skarsgård, who appears in the franchise, has teased that former stars like Meryl Streep could appear again, even though her character Donna died in the previous film. This suggests the film could use flashbacks, dream sequences, or other creative ways to bring beloved characters back.

Some reports also mention new potential cast additions, with producers considering younger performers such as pop artists to play new generations within the story, though nothing is official yet.
In summary, while Mamma Mia! 3 has not been officially released or fully defined, it is actively in development with support from the main cast and the original creative team. Fans can expect more musical joy, returning characters, and romantic, family-focused storytelling set against sunny island backdrops, once the official plot and release plans are finalized.
