Actress Naomie Harris, who plays Eve Moneypenny in "Skyfall," was among those touched by Union's words.
"I'm in the place you were," Harris said as she accepted the Shining Star award. "I feel as though I have traveled thousands of miles to actually listen to that speech, to learn, to be inspired and to be reminded of who I am."
Writer-producer Mara Brock-Akil cried throughout her acceptance speech, saying, "All I ever wanted to do was tell our story."
Other stars attending the luncheon at the Beverly Hills Hotel included Blair Underwood, Laila Ali, Star Jones, Jill Scott and Tracee Ellis Ross.
Grammy-winning singer Miguel performed his winning hit, "Adore," and rapper-actor Common did an impromptu freestyle during a brief technical difficulty, working the names of the six honorees into a quick rap.
