Wiki:
Ince was known as the "Father of the Western" and was responsible for making over 800 films. He revolutionized the motion picture industry by creating the first major Hollywood studio facility and invented movie production by introducing the "assembly line" system of filmmaking. He was the first mogul to build his own film studio dubbed "Inceville" in Palisades Highlands. Ince was also instrumental in developing the role of the producer in motion pictures. He later partnered with D.W. Griffith and Mack Sennett to form the Triangle Motion Picture Company whose studios are the present-day site of Sony Pictures. He then built a new studio about a mile from Triangle which is now the site of Culver Studios. Ince's untimely death at the height of his career after he became severely ill aboard the private yacht of media tycoon William Randolph Hearst has caused much speculation, although the official cause of his death was heart failure.
Eddie Izzard's website Cake or Death has a page on Peter Bogdanovich's 2005 film, "The Cat's Meow", which presents a speculative look at the events which unfolded on Hearst's yacht:
The plot concerns the demise of one of the guests on a merry weekend cruise in 1924. Though whispered about, the scandal was never much publicized.
"No, it was all hushed up," the director says. "But you can find references to it in alternative underground type of industry scandal books like Hollywood Babylon."
He first heard the story from Orson Welles, who heard it from Ms. Davies' nephew (Charles Lederer). It even appeared in the first draft of "Citizen Kane", inserted by Herman Mankiewicz. Co-writer Welles, contending the composite character of Charlie Kane was not a killer, took it out.
