"Desdemona" is a conceptually interesting film, although, as to be expected, it's very dated, especially in its static camera positioning--taking the proscenium arch stance throughout most of the picture. Additionally, the Kino print is of poor quality. In the film, Valdemar Psilander, the major Danish screen actor of the day, plays an actor who's preparing to play Othello on stage. In his off-stage life, he becomes enraged with Othello-like jealousy, which explodes on stage. The idea is that life is reflecting theatre and vise versa.
Mise-en-scène gets much more attention than camera-work in "Desdemona". Especially interesting is the use of mirrors, which take on an associative nature with cinema in Scandanavian films during this period. In this film, they nicely underscore the point of life and theatre reflecting each other. In another film from 1911, "Temptations of a Great City" (Ved Fængslets Port), the same director, August Blom, used mirrors to show action out of frame, which compensated some for the lack of camera movement and editing in the film. Anyhow, there are some good ideas within this short film, although they're better exploited in later incarnations with the benefit of advanced film-making.
