The Flintstones

William Hanna wanted to do a family-style series, but he and Joseph Barbera couldn't agree on the setting or the costuming. Suddenly, Hanna exclaimed, "Let's do it in a caveman setting! They won't wear clothes, they'll just wear animal skins!" After that great idea everything from then on "perfectly fell into its place."

In numerous episodes throughout the series, the capacity of passengers in both Fred's and Barney's cars changes back and forth from seating two passengers to four passengers.

First season episodes incorporated an ad for Winston Cigarettes into the opening credits (this version of the opening was removed for syndication). Due to the decision to use a standard opening and closing for syndicated versions of the episodes, numerous episodes have incorrect closing credits. Sixth & last season episode debuted with, No Biz Like Show Biz (1965) dropped the "Meet the Flintstones" closing credit song, in favor of footage of Pebbles and Bamm-Bamm singing "Let the Sunshine In." (a reminder of Fred Flintstone's dream, earlier in the musical program).

For the last half of Season 2, a truncated ending title was used. This end title still used the "Rise and Shine" theme, however the 10 second sequence where Fred puts out the milk bottles and closes the front door was removed, and the theme song was bridged to account for the gap. Unfortunately, the Season 2 DVD box set does not show this truncated end title, and as of 2006 this footage is still considered "lost".
