In the United States, there is a stereotype that the British are extremely well mannered and sophisticated. This is in spite of evidence to the contrary which seems to say they can be just as lowbrow and dopey as the rest of us. Sure, they have produced many classic films as well as television shows (such as "Downton Abbey" and "I, Claudius")....but they also have brought the world "The Benny Hill Show" and drivel like "The Adventures of Jane".
So what IS "The Adventures of Jane"? Well, apparently it is a movie based on a comic strip for adults and Jane is apparently very accident prone and always ends up having her clothing ripped off of her! Sophisticated? Hardly! And in the film, it's pretty much what you'd expect, as it's filled with very bad jokes (the sorts you'd expect to hear on stage in a burlesque-type review) and Jane standing about in her underwear.
Overall, this film was too broadly written, acted and directed to be seen as anything other than a bad little curio. Apparently, the plan was originally to make a series of these films but the British public, fortunately, did not embrace the movie and further movies were dropped. It's bad and difficult to watch....trust me on this!
