Thomas Cruise Mapother IV (born July 3, 1962), more commonly known as Tom Cruise, is an American actor and film producer. Forbes magazine ranked him as the world's most powerful celebrity in 2006. He has been nominated for three Academy Awards and won three Golden Globe Awards. October 10, 2006 was declared "Tom Cruise Day" in Japan; the Japan Memorial Day Association said that he was awarded with a special day because he has made more trips to Japan than any other Hollywood star.

His first leading role was 1983's Risky Business. After that, he starred in many top films and became a Hollywood celebrity, perhaps the most notable of these being the hugely successful 1986 film Top Gun.

He is also one of only three actors in the history of film to have seven consecutive US$100 million blockbusters, the two other being Tom Hanks and Will Smith.

Cruise is also known for his support of Scientology, and his criticism of psychiatry and anti-depressive drugs, which have attracted controversy and media interest.
