Creator Killer: While Julie Taymor's uncompromising attitude when dealing with the producers ultimately prevented Joe Roth's butchered re-edit from ever seeing the public eye outside of a few test screenings, it also killed any chance she had of becoming a major film director. She subsequently retreated back to the Broadway scene, with her only film work since being a couple of comparatively low-budget William Shakespeare adaptations.
Doing It for the Art: The homage to The Beatles was more important than the plot, hence a few songs and sequences that technically didn't advance the story at all.
Executive Meddling: Attempted, but failed. The studio decided the original cut of the film was "too artsy," and re-edited it to better suit mass audiences. However, Julie Taymor had enough clout to make sure she had Protection from Editors in her contract. She made them release her cut without any alterations, and even went so far as to get the studio to destroy all copies of their re-edited version.
