Busy is right...workaholic is more like it. I had no idea that Mr. Le Saint was also a director in the silent era, and for whatever reason, he stopped directing just before sound came in (his last directing credit is from 1926, and the first sound film, "The Jazz Singer," was released in 1927).
In his later years, he was definitely typecast as "Judgie-Wudgie;" the vast majority of his many parts are as judges, and he even played the Chief Justice in one film, "Gabriel Over The White House." Not to mention that he appeared with Charlie Chaplin ("Modern Times"), W.C. Fields ("You're Telling Me!"), and the Marx Brothers ("Horse Feathers"), as well as with the Stooges.
Here we have a journeyman actor who never became famous, but I'm sure he was never bored, either!
