In his introduction to "New Stories from the Twilight Zone", the series' executive story consultant Alan Brennert said that he tried to get "Opening Day" killed about twelve times "but everytime I thought I'd finally driven a stake through its heart the damned thing would rear up from the dead yet again."
"Opening Day" goes by another title, "Duck Shoot".
"The Uncle Devil Show" has no narration, an either the beginning or the end. Neither "The Shadow Man" nor "Opening Day" have a closing narration.
