What an amazing cinematic experience! Just as Porter's influence was starting to wane, he makes what is arguably his most visually stunning film. Though not as famous as "Life of an American Fireman", Rarebit Fiend is a clever, captivating piece of film history.
The 'plot' as such is irrelevant - what the film does is take opportunities to showcase as many new special effects as it possibly can. Tricks of space, dimension, time, both in-camera and on set, create one of cinema's first convincing nightmare perspectives. Predating the surrealist era by decades, Porter's film is a must see for all fans of non-linear and non-traditional film-making.
