This was a back-door pilot for a proposed spin-off series starring the Colton brothers, which never materialised.
Frank and Jesse's names are obvious references to the infamous outlaw James brothers' names, since as bounty hunters, they, too, are viewed by different people as either heroes or villains.
This was the only time all of the Coltons appeared together.
This was filmed the previous winter when production was still in Canada, as can be seen by bare trees, people's foggy breath, the winter skies, and end credits.
With this being intended as a pilot for a Coltons themed spin-off, it is barely a MacGyver story at all, with Richard Dean Anderson effectively just cameo guest starring in his own show, only appearing in the opening and closing scenes, with his scenes only adding up to approximately five and a half minutes in total duration.
