Fred MacMurray renewed his contract annually during the show's entire run.

William Frawley really enjoyed working on the show,and did not want to leave. To make matters worse,he was replaced by William Demearest,whom he hated in real life.

Although officially leaving after the show's fifth season in 1964-1965, Tim Considine's last appearance as Mike, the eldest son, was actually in the first episode of season 6 (the series' first in color). The episode opened with a brief scene showing Mike and Sally's (Meredith MacRae) wedding. The episode also "launched" Barry Livingston ("Ernie") as the new son. The characters of Mike and Sally were mentioned in the next two episodes, which dealt with Ernie's adoption, and in a subsequent episode when Charley and the boys thought Steve was getting married. Mike was referred to by name one last time in the first 1966-1967 episode, when the gang visited Steve's hometown. After this they were never referred to by name again for the remainder of the series, although Mike was indirectly referred to as, "the first of you" by Steve a few years later.
