Thomas Marvin Hatley (April 3, 1905 – August 26, 1986), professionally known simply as Marvin Hatley, was an American film composer and musical director, best known for his work for the Hal Roach studio from 1929 until 1940.
Hatley wrote many of the musical cues appearing in the Our Gang, Laurel and Hardy, and Charley Chase films.
His work in Laurel and Hardy's films Way Out West and Block-Heads earned him nominations for the Academy Award for Best Original Score.
Hatley went on to become a lounge pianist, and often remarked that he earned more money in that career than during his days at the Roach studio.
