Here’s a story from People magazine, at the time of Randall Dale Adams’ release. Here’s one from the L.A. Times. Both add some useful context, and the Times’ piece reveals that Adams was not Errol Morris’ intended subject when he came to Dallas to make a documentary:
Errol Morris had never heard of Randall Dale Adams when he came to Texas to make a movie in 1985. He was interested, instead, in a man named James Grigson, a Texas psychiatrist nicknamed “Dr. Death” because his testimony had helped send Adams and 26 others to Death Row.
In the course of his research, he came across Adams and his story. At first, Morris didn’t believe him. But as more and more facts checked out, he began to be swayed, and finally convinced. Thus began a three-year project that would become “The Thin Blue Line.”
Last year in the New Yorker, David Grann raised questions about another case where an innocent man may have been executed.
