Just three months before Roy Thinnes premiered in his own QM production vehicle: The Invaders (1967).
This is the second and final appearance Victor Millan makes in the series. His first appearance occurs in Second Sight (1966), which originally aired one week prior to this episode's original air date. Contrary to the police officer role he plays in his first appearance, in this second appearance he plays an Hispanic farmworker fearful of the police.
Dabbs Greer, who plays the hotel clerk, is making his fifth of six appearances in the series, each time in a different role.
