 This film starring Cagney, James (qv) as Chaney, Lon (qv) shows  Chaney making a scene in _Miracle Man, The (1919)_ (qv). That film  was based on a novel by Packard, Frank L. (qv) and its stage  adaptation by Cohan, George M. (qv), who acted in it himself (not  in the same part as Chaney, though). And in  _Yankee Doodle Dandy (1942)_ (qv), Cagney had played Cohan.
