"The Trial of The Century," involving the love triangle of a jealous millionaire husband (Harry Thaw) shooting a prominent architect (Stanford White) inside a busy NYC restaurant, received full treatment in Lubin Company's "The Unwritten Law." The 1907 film was based on the June 25, 1906 killing, with showgirl Evelyn Nesbit, who was seduced earlier by White, witnessing the murder.
The movie was cinema's first docudrama that re-created a true-life murder. What's interesting is Ms. Nesbit plays the role of herself in the film, while at the same time Thaw's murder trial was still to be decided. The love triangle was later portrayed in Richard Fleischer's "The Girl In The Red Velvet Swing" (1955)--with Joan Collins playing Evelyne-- and in 1981's "Ragtime"--with Elizabeth McGovern in an Oscar nominated performance as Ms. Nesbit.
