The party at the National Gallery included a special showing of "The Bowler and the Bonnet," a black-and-white documentary Connery made in 1969.
But Connery took center stage throughout the evening. He participated in a discussion on his film career and received a special award for outstanding achievement.
"Anybody in the film world, or who knows anything about movies, is a supporter because it has produced lots and lots of successes, and it will produce even more because we have a plan to develop it even further," Connery said of the festival.
The festival began specifically to showcase documentaries.
