To put things in context, John Barrymore’s Sherlock Holmes starts out has a college kid chasing after the mysterious Moriarty. Gustav von Seyffertitz the the villainous professor. Von Seyffertitz seemed to have it in for the Barrymore boys. He menaced John again in Don Juan and drove Lionel to madness in The Bells.
On the great Moriarty scale, I give von Seyffertitz a 7/10. Pretty darn good, especially considering that he is not in the film very much.
On an unrelated note, I love Moriarty’s brush-off and plan to use it next time I want to get rid of a college boy whom I have met only once.
