Quincy's first name was never revealed during the series. However, in one episode, one of his business cards was briefly seen and read "Dr. R. Quincy."

In the typical opening title sequence, near the end of the credits, there is a scene showing Quincy walking along talking his friend on the beach with people (extras) throwing a football in the background. As the ball is thrown toward the camera it passes off the screen to the left. Moments later a woman with a pink top and blue skirt stumbles into frame grasping her face and eyes. Her companions rush to her aid as she tries to brush sand or grit from her face. She is in obvious distress as is see by everyone's actions toward her, all except Quincy who obliviously walks on toward the camera continuing the scene. This was kept in the opening credits which is odd given that it is made up of snippets.

Many of the episodes that aired as part of the "NBC Mystery Movie" were edited down from 88 minutes in length to roughly 44 minutes in length when the show went into reruns in syndication.
