The producer of my film* played one of the Jack City guys and I have talked to him at length about it. [The other guy in the commercial, is also in my film.]
At the time, they were on a show called Furniture Guys, which was on PBS and The Learning Channel. He said that they were brought in quickly and there was no intention on expanding on their characters. I will ask him if he has anything to add.
*Which we shot in Germantown, Philadelphia, which was where Mannequin: On the Move was also shot.
