Ben Blue (September 12, 1901 – March 7, 1975), born Benjamin Bernstein, was a Canadian-American actor and comedian.
In the 1920s Bernstein joined a popular orchestra, Jack White and His Montrealers. The entire band emphasized comedy, and would continually interact with the joke-cracking maestro. Blue, the drummer, would sometimes deliver corny jokes while wearing a ridiculously false beard. The band emigrated to the United States, and appeared in two early sound musicals: the Vitaphone short subject Jack White and His Montrealers and Universal's feature-length Technicolor revue King of Jazz.
Blue left the band to establish himself as a solo comedian, portraying a bald-headed dumb-bell with a goofy expression. Producer Hal Roach featured him in his "Taxi Boys" comedy shorts, but Blue's dopey character was an acquired taste and he was soon replaced by other comedians. Later in the 1930s he worked at Paramount Pictures, notably in The Big Broadcast of 1938, and later at Metro-Goldwyn-Mayer. In 1950, he had his own short-lived TV series, The Ben Blue Show, and was also a regular on The Frank Sinatra Show.
