Hugh Milburn Stone was born in Burrton in Harvey County in central Kansas, the son of Herbert and Laura Stone. He began his screen career in the 1930s, having been featured in Monogram Pictures' series of "Tailspin Tommy" adventures. In 1940, he appeared with Marjorie Reynolds, Tristram Coffin, and I. Stanford Jolley in the comedy espionage film Chasing Trouble. Also in 1940 Stone co-starred with Roy Rogers in the movie Colorado wherein he played Rogers's brother-gone-wrong acting under the alias Donald Mason, a southern sympathizer. He also played the liberal minded warden in Monogram Pictures', "Prison Mutiny", in 1943. Stone was signed by Universal Pictures in 1943 and became a familiar face in its features and serials. One of his film roles was a radio columnist in the Gloria Jean-Kirby Grant musical I'll Remember April. He made such an impression in this film that Universal gave him a starring role in the 1945 serial The Master Key. If you look closely, in the early part of Gone With the Wind, you will see both Stone and George Reeves, on the porch at O'Hara's Tara.
