I Wanted to See Lars!
It drove me up a wall that we never saw Lars! Did anyone else want to see him! They teased the audience about him on MTM. I really thought they'd show him in the episode when he has a fling with the Happy Homemaker. It was the first time I ever saw an entire show revolve around an unseen characters.
A lot of shows pull that stunt of the unseen yet talked about character such as Maris on Frasier, Norm's wife Vera on Cheers, Carlton the Doorman on Rhoda,etc. I read that they considered casting an actress as Maris but it was better to leave her to the audience's imagination. They didn't think they could cast someone as good as what the audience already pictured in its mind.
I suppose the audience all imagined Lars in different ways. But I wanted to see him! I wish there would have been a picture in a frame that Phyllis kept on her dresser so we could have had a glimpse. Or they could've done a flashback episode when Lars and Phyllis were newlyweds. A different actress could've played a very young Phyllis with a young Lars as a medical student. Who could've played him??
