Bobby Mack on AllMovie

A wizened little comedian from Scotland, in American films from the 1910s, Bobby Mack (sometimes known as Robert Mack) is best remembered today for playing Johan Kellerman, the student orderly turned Royal Major Domo in Ernst Lubitsch's romantic The Student Prince ([1927] the scene in which the king's supercilious ministers are forced to doff their hats to the lowly Mack, over and over again, is priceless). Before that, Mack was Derby Ghost in Vitagraph's 1921 version of the ever-popular Black Beauty and Sir Pitt Crawley in Vanity Fair (1923). He became a cameraman after the advent of sound, assisting Lucien Andriot on Raoul Walsh's epic The Big Trail (1930).
