classics". The Taming of the Shrew also became a notable critical and commercial success. He had another quick collaboration with Zeffirelli narrating the documentary, Florence: Days of Destruction, which was about the 1966 flood of the Arno that devastated the city of Florence, Italy; the film raised $20 million for the flood relief efforts. By the end of 1967, the combined box office gross of films Burton and Taylor had acted in had reached $200 million. According to biographers John Cottrell and Fergus Cashin, when Burton and Taylor contemplated taking a three-month break from acting, Hollywood "almost had a nervous breakdown" as nearly half the U.S. cinema industry's income for films in theatrical distribution came from pictures starring one or both of them. Later collaborations from the Burtons like The Comedians (1967), which was based on Graham Greene's 1966 novel of the same name, and the Tennessee Williams adaptation Boom! (1968) were critical and commercial failures. In 1968, Burton enjoyed a commercial blockbuster with Clint Eastwood in the World War II action film Where Eagles Dare; he received a $1 million fee plus a share of the film's box office gross. According to his daughter Kate Burton, “He did that one for us kids, because we kept asking him, 'Can you do a fun movie that we can go see?" Eastwood thought the script "terrible" and was "all exposition and complications". He asked the film's producer Elliott Kastner and its screenwriter Alistair MacLean to be given less dialogue, later remarking "I just stood around firing my machine gun while Burton handled the dialogue." Burton enjoyed working with Eastwood and said of the picture that he "did all the talking and [Eastwood] did all the killing". Burton's last film of the decade, Anne of the Thousand Days (1969) for which he was paid $1.25 million, () was commercially successful but garnered mixed opinions from reviewers. Noted British film critic Tom Milne of Time Out magazine believed that Burton "plays throughout on a monotonous note of bluff ferocity". Conversely, Vincent Canby of The New York Times appreciated Burton's portrayal of the English monarch, noting that he "is in excellent form and voice—funny, loutish and sometimes wise". Anne of the Thousand Days received ten nominations at the 42nd Academy Awards, including one for Burton's performance as Henry VIII of England, which many thought to be largely the result of an expensive advertising campaign
