In May, Mendes took the stage at CinemaCon with the four actors set to star in his unconventional biopic project: along with Keoghan as Starr, fans will see Paul Mescal as Paul McCartney, Harris Dickinson as John Lennon, and Joseph Quinn as George Harrison.

Starr said he gave “extensive notes” to director Mendes while fact-checking the scripts. The scenes in particular that depicted Starr’s family and his first wife, Maureen Starkey Tigrett (whose casting has not yet been announced), were among the sequences that Starr urged to have reworked.
