Tale of the Titanic disaster in four parts. The first three tell the same basic story but through the eyes of passengers in 1st, 2nd, and 3rd class (steerage). The story lines overlap and all meet in the same disastrous finale: the sinking of the ship.
Although there are no big names in the cast, several are familiar faces (Maria Doyle Kennedy, Linus Roache, Toby Jones, Steven Waddington, Stephen Campbell Moore, Celia Imrie, James Wilby, Linda Kash).
To my knowledge this is the only "Titanic" story that has included the real-life Dorothy Gibson (played by Sophie Winkleman), an American movie actress, who survived the disaster. Back in the US, she was rushed into "Saved from the Titanic" within a month of the sinking. She played herself, recounting the disaster, but was so overcome by grief, she suffered a nervous breakdown during the filming and retired from acting. The 1912 film was an absolute sensation, one of the biggest hits of the time. The film was tragically lost in a 1914 studio fire.
