Williams has won 23 Grammy Awards, seven British Academy Film Awards, five Academy Awards, and four Golden Globe Awards. With 50 Academy Award nominations, Williams is the second most-nominated individual, after Walt Disney. In 2005, the American Film Institute selected Williams's score to 1977's Star Wars as the greatest American film score of all time. The soundtrack to Star Wars was additionally preserved by the Library of Congress into the National Recording Registry, for being "culturally, historically, or aesthetically significant". Williams was inducted into the Hollywood Bowl's Hall of Fame in 2000, and was a recipient of the Kennedy Center Honors in 2004 and the AFI Life Achievement Award in 2016. Williams composed the score for eight of the top twenty highest-grossing films at the U.S. box office (adjusted for inflation).
