“I hope that God opens her eyes and lets her breathe and lets her brain work, and she gets a second chance,” Costner said in an interview with “Nightline” co-anchor Juju Chang last Friday at the W Hotel in Hollywood.
Several hundred people gathered Monday for a vigil in Brown’s honor at the Amphitheater at Riverdale Town Center in Riverdale, just outside of Atlanta.
"The facts are the facts right now, that she's sitting here, fighting for her life, surrounded by the people who love her the most," Costner said.
Costner has long been close with the Houston family. He produced and co-starred in the 1992 film, “The Bodyguard,” with Houston, and it was Costner who suggested they use the song, "I Will Always Love You," as the movie’s signature ballad.
Not only did the movie help launch Houston to mega-stardom, the song, “I Will Always Love You,” became her anthem, earning three Grammys and a spot on Billboard's "Greatest Songs of All Time” list.
"My thoughts are probably similar to everyone, which is, obviously, the similarities, what's going on, the worry that this might have happened again," Costner said, adding that he is hoping Brown gets “to have a second chance at this most precious life that we are all given.”
