Fakt ten potwierdza siostra Stu, Pauline Sutcliffe, w książce "THE BEATLES' SHADOW. Stuart Sutcliffe & his lonely hearts club"
Cytuj:
The James Dean tag has always been a red herring, for Stuart modelled himself on another actor: the image was originally inspired by the Polish star Zbygniew [sic] Cybulski, whom Stuart had first seen in Ashes and Diamonds at the art school film society. [...] Stuart was taken by the style of Cybulski, the lookalike of a young Jean-Paul Belmondo, with wavy, swept-back hair, and cool sunglasses and manner. For Stuart, Cybulski was playing him, up on the big screen.
