In fact, Callahan spent the better part of his career at Monogram, remaining at the "MGM of the South" through its metamorphosis into Allied Artists. He was principal writer for the studio's gimmick-laden Charlie Chan epics, and also scripted all three "Shadow" features, serving as associate producer for the final entry in this series, The Missing Lady (1946). George Callahan's best-known accomplishment was the risible The Babe Ruth Story (1948), which he co-scripted with sports journalists Bob Considine and Grantland Rice. ~ Hal Erickson, Rovi
