Bud Ekins did the stunt motorcycle work for this TV Pilot and series, he was best friends with Steve McQueen, and did the jump in The Great Escape.
The series was not shot in a studio but on the road, and in order to allow the film to be reviewed after each day's shooting the film was developed in a special semitrailer that followed the shooting from one location to the next. A second identical setup was used for filming the series "I Spy".
The theme song for the pilot was "Wayfaring Stranger", written by Johnny Cash.
Jim sings Wayfaring Stranger in a duet with Bonnie.
The station wagon driven by "Businessman" in the opening title sequence was Stu Klitsner's own vehicle.
