 DATE: Ennis gets a postcard from Jack which reads, "Ennis, see you  in a couple weeks, fish should be jumping. Jack." The postmark is  from Childress, Texas, dated July 1972. A couple of weeks later,  Jack is driving a blue Ford truck. Ford only produced this specific  truck grill in 1976 and 1977. In a following scene, Ennis and Almas  divorce is granted 6 November 1975. The blue truck should not appear  in a 1972 scene.
