Why no John Williams?

Rating: 9/10 (20 November 2005)

Greatly enjoyed the film but could not at first understand why the quality of the music was so poor. I assumed that John Williams had been suffering from Potter overload, so unimaginative and repetitive was the score, until eventually the credits revealed the explanation, he didn't actually write the music for this episode of the saga, although a Williams theme from previous episodes was used endlessly and, apart from moving it into a minor key, almost without variation. For me, so much of the special impact made by the screen images and action in the first three films was enhanced and intensified by Williams' magical (literally) melodies and scoring, that the lack of those vital elements in the Goblet of Fire were deeply and disappointedly missed. Does anyone know why he didn't work on this latest film?
