Mary Crosby on AllMovie

The youngest child of actor/singer Bing Crosby and his second wife Kathryn Grant, Mary Crosby made her first professional appearances in the company of her siblings in Bing's Christmas-season TV specials of the 1960s and 1970s. As an adult actress, Mary seemed determined, either by accident or design, to go against the grain of the "wholesome" image perpetrated by her father. As the whole world knows, it was Mary Crosby who, in the guise of "Kristin Shepard," shot J.R. Ewing (Larry Hagman) in that fateful 1980 episode of TV's Dallas.
