Director Steven Spielberg and late author Philip K Dick have been welcomed into the Science Fiction Hall of Fame in its first induction ceremony.
Spielberg has been a leading Hollywood director for 30 years
Spielberg made seminal films such as ET and Close Encounters of the Third Kind while Dick, who died in 1982, was one of the leading US sci-fi novelists.
The hall of fame already includes 36 sci-fi icons including writers Arthur C Clarke, Jules Verne and HG Wells.
It is part of a museum opened in 2004 by Microsoft co-founder Paul Allen.
Friday's ceremony also honoured artist Chesley Bonestell, who created special effects for films such as War of the Worlds, and stop-motion animator Ray Harryhausen.
Dick wrote 44 novels, which inspired films including Blade Runner, Total Recall and Minority Report.
The hall of fame was founded at the University of Kansas in 1996 before moving to Seattle's Science Fiction Museum, which opened last year.
