The piano man's world is hitting a sour note. The director of the unauthorized biopic 'Billy and Me' just unleashed a scathing response to Billy Joel's camp. Joel's team previously slammed the film, calling it 'fiction' and 'not sanctioned.' Now, the director is reportedly challenging their claims, setting the stage for a dramatic showdown over the film's accuracy. This escalating war of words could redefine unauthorized biopics.
