The temple runs were often taped without an audience, especially in the third season. Since tapings lasted until as late as 1AM, and the show taped multiple episodes worth of every segment, by the time the temple runs were taped, the studios had often closed for regular guests and an audience track was used to make it sound like there was an audience watching.
The Temple Guards were actually the stage assistants. Occasionally, some of the writers would also take this task.
In the history of the show, only thirty-two players ever successfully retrieved an artifact from the room at the center of the temple.
In the Room of the Golden Idols, no player ever successfully "hugged an idol" to progress downward from the room. Only one player ever tried doing this and the door didn't open. Likewise, in the Treasure Room, the room that replaced the Golden Idols, only one player ever opened the treasure chest to progress downward.
Each contestant was allowed to keep the same team T-shirt that he or she wore during the course of the program. However, contestants on the Silver Snakes team were given facsimiles afterwards since the T-shirts they wore during taping were specially designed to show up better on film.
