I add a review if a film has no yet received one. I recently saw this at the Gothique film society screening at the Cinema Museum in London, it should be noted the intertitles were live translated as they are in Italian (it's the only known print), this is my review...
Oddity, the first film to feature a human brain transplanted into a gorilla, however this is only a minor sub-plot, in the main it's a story of newspaper rivalry, with skulduggery afoot, and a junior reporter as hero. It's a plot that's way too narratively driven to work as a silent, there are endless intertitles to try and explain what's what, the only cinematic bit of the film is some crazy stunts near the end, which don't make sense from a story point of view. In it's favour, it's rare and there is a man in a monkey suit.
I waited a bit before posting this, as I hoped someone would beat me to it with a more positive review.
