     When the Japanese attacked America's ships at Pearl Harbor on 7 December 1941,they did it

secretly. The makers of the movie Pearl Harbor have behaved differently.

     The noise about Pearl Harbor,made by Disney,has reached its highest point with its premiere (首次

公演) before the movie opens in cinemas across the US at the start of the Memorial Day holiday

weekend,a time to recall national heroes who sacrificed their lives on the battlefield.

     As Ben Affleck is the main star,the movie seems sure to become a success in the United States at

least.

     At almost three hours in length,it promises to be a good old Hollywood movie.There is a love story.Affleck and his co-star,Josh Hartnett,both fall in love with the navy nurse,Kate Beckinsale and,of course,there is much human courage and love of country.

     It's certain that Disney will be accused of "changing" history.The showing of actual events in a movie

always causes arguments.

     Bits of the story are deliberately not mentioned in the movie.It does not address the theory held by

some historians that President Franklin Roosevelt knew about Japan's intention to attack the ships in

Pearl Harbor.It is said he did nothing,as he was aware that such a blow would allow him to take

America into the Second World War.

     Japan remains sensitive about being accused of wartime atrocities (暴行).And Disney is sensitive

about its business in Japan,where it has a theme park.

     Not all the reviews of the movie have been full of praise.A reviewer for Newsweek,who was given

an early preview,acknowledged that the 40-minute sequence (连续镜头) showing the attack itself was

powerful.The attack comes quite late in the movie,however,and the reviewer was less impressed with

the characters and the love story.

     "Almost every line of the dialogue sounds like it comes from an old movie," the reviewer wrote.
