This short is one of the extras included with MR. MOTO IN DANGER ISLAND. It's a 15 minute film about the Moto series--with lots of behind the scenes information and analysis. While there's a limit to just how good this can be given its short time constraints, the film does a nice job of providing information about the character and Peter Lorre that fans will no doubt enjoy. It does this with quite a few interviews--including with the guy who wrote the biography of the author of the Moto books as well as the author's son.
Overall verdict--not absolutely necessary viewing but a good and enjoyable DVD extra.
