Pete Best's Niece to Have Significant Role in Sam Mendes' Films about The Beatles

The ensemble for Sam Mendes upcoming four-part Beatles biopic continues to expand, with an intriguing new addition: a family member of the groups original drummer, Pete Best. Actress Leanne Best, Pete Bests niece, has been selected to portray John Lennons aunt, Mimi. Mimi played a crucial role in Lennons upbringing after his father departed and his mother, Julia, began living with another partner.

Even after Lennon reunited with his mother, Mimi remained a central figure in his life, especially following Julias tragic death in a car accident during Lennons teenage years. Her influence was so significant that Lennon later incorporated some of her expressions into the lyrics of Shes Leaving Home, such as Sacrificed most of our lives and Never a thought for ourselves. Mimi was known for her strict guidance, at times discouraging Lennon from pursuing music professionally, suggesting instead that he focus on more conventional careers.

Leanne Best has built a steady acting career since the mid-2000s, appearing in projects including the BBC series Ripper Street and Star Wars: The Force Awakens. Her uncle, Pete Best, was the Beatles original drummer from 1960 to 1962 before being replaced by Ringo Starr. Casting for Pete Best in the Mendes films has not yet been announced.

Additional casting news reveals James Norton will play Beatles manager Brian Epstein, David Morrissey will portray Paul McCartneys father, Jim, and Bobby Schofield will appear as the bands road manager Neil Aspinall. Daniel Hoffman-Gill is set to play longtime assistant Mal Evans, Arthur Darvill will take on journalist-turned-press officer Derek Taylor, and Adam Pally will depict Allen Klein, whose management period was controversial just before the Beatles breakup.

The cinematic event, The Beatles A Four-Film Event, is currently in production, with releases scheduled to begin in April 2028. The main cast includes Paul Mescal as Paul McCartney, Harris Dickinson as John Lennon, Joseph Quinn as George Harrison, and Barry Keoghan as Ringo Starr. Female leads recently confirmed are Saoirse Ronan as Linda McCartney, Aimee Lou Wood as Pattie Boyd, Anna Sawai as Yoko Ono, and Mia McKenna-Bruce as Maureen Starkey.

Author’s Analysis: Family Ties Strengthen Mendes’ Beatles Vision

Adding Leanne Best, niece of original Beatles drummer Pete Best, as Mimi Lennon, demonstrates Sam Mendes’ attention to authentic connections within the Beatles’ story. Mimi Lennon’s role in John Lennon’s upbringing was pivotal, and casting an actor with a family link to the band brings an added layer of historical resonance.

This choice complements the broader ensemble, which includes notable actors portraying key figures in the Beatles’ personal and professional lives. From James Norton as Brian Epstein to David Morrissey as Jim McCartney, the casting strategy blends established talent with emerging actors, ensuring depth across multiple storylines.

The decision also highlights Mendes’ commitment to detail: Mimi’s influence on Lennon’s lyrics and character is critical, and Leanne Best’s performance could provide insight into Lennon’s formative years. With production underway and a 2028 release, this family connection hints at the meticulous approach the filmmakers are taking to honor the Beatles’ legacy.
