This is actually a very elaborate fiction film for 1898. Made by Georges Méliès, it lasts over three minutes, when most films during the period lasted about a minute or less. Early cinema historian Frank Gray refers to this film as having consisted of three shots and 60 meters length. Yet, I can't precisely distinguish or separate shots or scenes in it, as the entire film takes place from a fixed framing and long-shot perspective. One could go to either extreme: saying that this is a single shot-scene film since its perspective is stationary, or you could say it consists of dozens of shots, including the trick splices for appearances, disappearances, substitutions and stop-motion animation, which is to say this film is a series of jump cuts.
"The Astronomer's Dream", however, does contain a three-part structure, I'd say. The bookend parts are of the astronomer safe within his laboratory, with the longer, middle part being the nightmare. There are also at least three slightly different decors used: the outer one with the telescope and the entire laboratory; a tighter, less furnished, yet similar one for closer views of the moon during the dream; and, briefly, a wall. Moreover, as indicated by this film having three entries in the Star catalogue, it was available to exhibitors in three parts, which was common then, as films were generally sold in 20-meter lengths. Regardless, this is a sophisticated narrative and production for its time.
The following year, Méliès would produce his first féerie film (fairy film), "Cinderella", which consists of at least four distinct scenes transitioned by dissolves. "Cinderella", albeit, is in the tableau, theatrical style of stationary shot-scenes, but it does distinguish spatially separate scenes for a more advanced narrative construction. One fiction film in 1898, Robert W. Paul's "Come Along Do!" also contained two spatially separate scenes with action continuing across them. "The Astronomer's Dream", however, was Méliès's then most elaborate and sophisticated dream or trick film, although it does contain a fairy godmother type in the goddess Phoebe, who protects the astronomer from attacks by demons, the moon and the rest of the nightmare. It's purely part of what Tom Gunning has referred to as "the cinema of attractions"; the attraction here being the magic or tricks accomplished mostly through substitution splices (a.k.a. stop substitutions), as well as theatrical props and transitions and a brief chalkboard animation within the scene. Today, these trick films hold up well and remain at least amusing because of Méliès's wacky and imaginative humor; their primitiveness is even part of their charm.
