While there are so many actors that portrayed Sherlock Holmes over the years and the discussion about the most faithful one could go on forever, one thing is certain: nobody looked more similar to the original Holmes illustrations than Arthur Wontner. His resemblance to Sidney Paget's illustrations is truly uncanny, it is as if he was actually modelling for those... which is impossible of course as those were made some 30 years before this film. Of course that similarity alone would not be enough to make him a good Holmes, but fortunately his portrayal of the famous detective is also excellent and very close to the novels.
Ian Fleming gives a sometimes bit wooden, but otherwise also very good portrayal of Watson and even thought at points the film does make fun of him not being able to keep up with Holmes, he definitely is not reduced to being a comic relief (as it happened to Nigel Bruce way too often) and is portrayed as a trustworthy friend and helping hand for Holmes. The rest of the cast is also fine, except maybe Norman McKinnel, whose overacting gets a bit annoying at times.
And while several of the Rathbone movies wandered off very far from the source material, this movie, even though it is not flawless, stays true to Doyle's spirit. It is based on two shorts, The Final Problem and The Empty House (which were actually the last before and the first after the detective's The Great Hiatus), borrowing from both's plot, but it also adds new elements to the mix and the result is a bit messy at points. It stars with a bank watchman getting killed during what appears to be a robbery, but we soon learn that apparently no money was stolen. As we go on a young man who likes to cheat during card games gets involved in the story along with her sister (played by the beautiful Jane Welsh), we have Moriarty giving orders while hiding behind the painting of a sleeping cardinal (hence the film's title), a shoemaker who is not what he seems to be and Inspector Lestrade, played by Philip Hewland, being completely unable to follow Holmes' thinking. So, we have a lot going on, but the story is somewhat strained at times, however it isn't much of a problem really, and the good performances, along with the witty dialogue more than make up for it.
The Sleeping Cardinal eventually spawned four sequels and while unfortunately one of those, The Missing Rembrandt is lost, all the others are in public domain now, so they are very easy to come across. This was also considered a lost film for a long while, but now there are obviously at least two copies available and the version I came across was pierced together from those. The majority of the film came from a copy with quite OK sound and picture quality, while a few short scenes (about 5% or less of the film) that were probably missing from that print are from another copy with way inferior picture quality. But overall this version is very watchable, unlike some of the copies described in older reviews. The film was also released in the US (screed under the somewhat sensationalist title, Sherlock Holmes' Fatal Hour) where it proved to be a surprise hit and I wouldn't be too surprised to learn that the series' (that run from 1931 till 1937) success was an inspiration for 20th Century-Fox to try their hands on a Holmes movie in 1939.
