Despite Greg Morris and Phil Morris playing father and son, they are father and son in real life.
"The Condemned" was one of four episodes of the 1960s "Mission: Impossible" that were remade during the 1988-89 television season. (A strike by the Writer's Guild in Hollywood initially precluded new scripts from being written for the series "reboot," so the producers of the new series initially decided to re-use 13 scripts from the original version.) Ultimately, four scripts were recycled; besides this one, they were "The Killer," "The System," and "The Legacy." This episode had originally been broadcast January 28, 1968.
The "John Truman" who is credited with the "story" for this episode is actually writer Laurence Heath, who wrote more episodes of the original Mission: Impossible than anyone else. Heath objected to the "recycling" of his original screenplay from January, 1968 as the source material for this episode during the 1988 writer's strike in Hollywood. While he could not legally prevent the re-use of his screenplay, he was able to have his name removed from this episode.
