Starring: Robert Conrad, Dick Cangey, Ross Martin, Whitey Hughes
The Night of the Gypsy Peril - S2-E18
Continuity mistake: The final scene shows a government official entering the private car to take delivery of the sultan. The open door shows that it is pitch black outside, but the final shot of the private train departing shows a very blue sky. (00:48:05 - 00:49:05)
The Night Dr. Loveless Died - S3-E4
Continuity mistake: In the opening scene, a cowboy sitting atop the balcony above Big Brad's Bar gets up and approaches the balcony's edge twice.
Trivia: Due to the rigorous stunts he performed, actor Robert Conrad would often rip out the seat of his already too tight pants.
