Barbara Rush's most famous film was When Worlds Collide (1951), which had Frank Cady (who played Sam Drucker, the general store fellow on "Petticoat Junction"). Frank also played Pa Tater in Hearts of the West (1975), with Jeff Bridges. Jeff is about to make Crazy Heart (2009) with Maggie Gyllenhaal, who, we all know, was in The Dark Knight (2008) with Heath, and in Donnie Darko (2001) with Jake. Heath :: BBM :: Jake.
