A word on intertitles
Since silent films had no synchronized sound for dialogue, onscreen intertitles were used to narrate story points, present key dialogue and sometimes even comment on the action for the cinema audience. The title writer became a key professional in silent film and was often separate from the scenario writer who created the story. Intertitles (or titles as they were generally called at the time) often became graphic elements themselves, featuring illustrations or abstract decorations that commented on the action of the film or enhanced its atmosphere.
In the silent film era, films were as much a literary as a filmic medium. I’m quite sure you could ‘watch’ the film by reading the intertitles.
Coming back to Dr. Pyckle and Mr. Pryde, I find the humour in sentences such as “England in the 19th century was not all that it might have been — It might have been Italy but wasn’t,” and “We squirm under the tumult of Good and Evil ever — warring within us, yet were Science to separate them, Bad would flourish. Crime run riot — even Saxophone players would be tolerated,” quite refreshing for 1925, when this film was released. We sometimes think that Monty Python started this kind of absurd humor, but clearly that is a mistake. To my knowledge the earliest modern instance of this kind of humor is Alfred Jarry‘s Ubu Roi, and going further back in the history of derision there is Rabelais and even before that there is the Facetiae by Poggio.
