Danny Bonaduce would often struggle with his lines, especially during the script readings. It turned out that he was dyslexic. However, he also had an eidetic memory, in which case, he would memorize his own lines as well as everyone else's. He stated that this would often get him on the bad side of his fellow cast members when he would correct them or state their lines for them when they couldn't remember.

In her autobiography, Shirley Jones said she got along with most of her co-stars, except for Dick Clark and Ray Bolger. She said she did enjoy working with Jodie Foster, and that everyone in the cast predicted Farrah Fawcett would become a big star.

Many companies, especially Columbia Pictures, were making a fortune off of David Cassidy and his image, and his contract didn't require them to pay him any royalties, nor even ask his permission. Even girls who paid money to join the David Cassidy fan club had no idea that their allowances were lining the pockets of people he didn't know, or authorize to use his name. He was only able to change the terms of his contract when his manager realized that he'd been nineteen when he signed. The legal age back then was twenty-one, thus making his initial contract null and void. His manager was finally able to renegotiate and give him a piece of the action, as well as a new weekly salary reflective of his star status. Initially, David Cassidy was only earning a flat salary of six hundred dollars per week.

When David Cassidy announced that he was leaving the show due to exhaustion, the producers came up with two different ideas to replace him.

Prior to getting the role of Shirley Partridge, Shirley Jones was one of the original choices to play Carol Brady on La tribu de los Brady (1969). However, Jones refused the role because, as she put it, she didn't want to be known for "pulling a pot roast out of the oven every week", and at least with the role of Shirley Partridge, she would be portraying a working mother, which Carol was not. Interestingly, both shows ran back-to-back with each other on ABC's classic early 1970s Friday night line-up.
