Beginning with this episode, James Gregory, Steve Landesberg and Ron Carey are added to the opening credits. Gregory would only be billed in the opening credits for the fourth season, possibly due to actually only appearing in eight out of the seasons' twenty-three episodes.
Mr. Binder enters on page 21 of Reinhold Weege's script. His first name was originally William, "a man in his forties" who "wipes perspiration from his upper lip constantly" and "extends a perspiring palm" when he shakes Barney's hand. His name becomes "Bruno" in the series. This was the character's first appearance.
