There were three Hollywood stars aboard the yacht the “Splendour” the night actress Natalie Wood died in late November 1981. Natalie, Her husband, Robert Wagner, and actor Christopher Walken, who was then co-starring alongside Natalie in the 1983 film, “Brainstorm.”

Dennis Davern, who captained the “Splendour,” was also aboard that night, and claims he witnessed much of what went on in the hours leading up to Wood’s death. He claims there was an argument that started in the salon of the boat.

“Natalie was getting so upset because of the way RJ (Wagner) was acting. He was being extremely jealous and that’s when he picked up a bottle of wine and he smashed it on that table. Glass went all over us - and the whole inside of the salon of the boat.”

Dennis says Christopher Walken retreated to his stateroom in the forward part of the boat, while Natalie and Robert continued the argument in their room below deck. “When everything got quiet I thought ‘Something just isn’t right,’” Dennis continues, claiming that’s when found Wagner standing at the back of the boat. “And he looked at me and he said, ‘Natalie’s missing.’"

Robert Wagner adamantly denies any involvement with the drowning of his late wife, Natalie Wood, and has never been charged in connection to her death.
