The Catholic priest that conducted Robbie's son's baptism was a real Miami priest, the Rev. Raul Angulo of St. Patrick's Catholic Church (now retired from the Archdiocese of Miami), though the scene was shot at St. Mary's Cathedral.
During the conference table scene, the camera tracks around a full 270º, ending up with Olmos in the position where the camera had originally been. He was standing outside the door when the scene started and slipped into the room silently in his stocking feet, hitting his mark moments before the camera reached its final location.
The Shelbourne Hotel is still in existence, now a luxury beach resort.
1960s' crooner legend Frankie Valli had his second acting credit for this episode. He would later have a recurring role in The Sopranos (1999). In the 70s he scored a major hit that brought him into the disco era in a big way, followed by another enormous hit with the theme song to Grease (1978). He would have quite a few TV and movie roles in the 80s and 90s. According to Crockett, Valli's character was involved in crime back in the 40s. In real life, Valli was in his fifties when this episode was filmed and at least a decade younger than the character.
At one point, Robbie tells Crockett, "For the first time since we landed back in the world, I feel like a man!" referring to their return from the Vietnam War. This phrase would later be used for the title of Back in the World (1985), which would involve another of Crockett's Vietnam buddies and would focus on the ongoing drug trade from the Vietnam area.
