A little-used private entrance to Perry's office is shown in this episode. After his conversation with Durant at the circus, Perry goes back to his office and enters through the door next to the balcony. In the past that door has been the entrance to a conference room but apparently the room can access the hallway without going through the reception area, since Perry had to tell Della on the intercom that he was back in the office.
Last of three cases with Lillian Bronson as the only female judge in the series.
At the time this episode was made, the producers of Perry Mason were struggling to cast an actor to replace William Talman, who had been dismissed from the show while facing a morals charge. This is one of three times Kenneth Tobey played Deputy D.A. Alvin, in essence "auditioning" to get the role on a permanent basis. The issue was eventually resolved when Talman was brought back to resume his portrayal of Hamilton Burger; Talman remained with the series until the end of its nine season run.

The idea of a killer on the run "hiding" in plain sight under clown make-up was also a plot element in Cecil B. de Mille's 1953 Best Picture Oscar winner The Greatest Show on Earth.
Throughout the series the type of garb Perry's clients wear while they're in jail is different from episode to episode. Some wear a denim jacket and blue collar work clothes (as Felix is wearing when Perry visits him), others wear plain cotton clothing, and still others wear the clothing they had on when arrested.
