My complaint was similar to my dismissal of "The Naked Alibi." So much high quality talent wasted in a production that failed to deliver more than middling to mediocre results from what ought to have been a dynamite movie. Why go to the kitchen if you're not going to use the quality ingredients to cook something special.
SPOILER: "Street of Chance" tosses in a few plot points about fascist wannabes (much like the better film "This Gun for Hire") that add nothing to the movie. The television adaptation of "The Black Curtain" wisely avoids this tacked on nonsense.
Garrett Fort did have a few more scripts worth mentioning "The Man in Half Moon Street" and "Blood on the Sun" being a few late entries.
My suspicion is that Fort's unhappy end was driven in part by his being swindled by con artists posing as religious mystics.
Richard Basehart brings an intensity to "The Black Curtain" that Burgess Meredith lacked. Basehart probably benefited from having a talented director (Sydney Pollack) guiding this episode of "The Alfred Hitchcock Hour."
