Question: Who was the director of the 1994 British biographical historical comedy-drama film for which Sir Nigel Barnard Hawthorne  was nominated for the Academy Award for Best Actor for portraying King George III?
Sentence (from "The Madness of King George"): Modern medicine has suggested that the King's symptoms were the result of acute intermittent porphyria, although this theory has more recently been vigorously challenged, most notably by a research project based at St George's, University of London, which concluded that George III did actually suffer from mental illness after all.
Relevant evidence: No
