- Blooper: At the start of one 1982 episode, Martindale refers to the champion as a "lady", but realizes his mistake after the champion, architect Bill Peters, is introduced.
- Fan Nickname: During the years it was rerun on GSN regularly, it was referred to as "The Fort Knox of Game Shows".
- Franchise Killer: Negative reception to the 1990-91 revival seems to have killed interest in the show, as no attempts have been made to revive it.
- Keep Circulating the Tapes: Complicated.
- Only two episodes of the NBC nighttime version note and the first four episodes of the CBS run note circulate. Some Barry episodes are available for viewing at the Paley Center for Media in New York.
- Of the 197886 nighttime run, GSN has never shown anything from 1981 to 1983, along with the tail end of the final season.
- The 1990s version reran on the USA Network from 1993 to 1994, but hasn't been seen since. (This might have to do with ITC, the people who brought us Thunderbirds and The Muppet Show, distributing it (though by this point they weren't doing much other than making the occasional TV movie) having been successively bought and sold; Polygram and then Universal owned the company itself for a time in the late 1990s, but its library (or at least the good stuff) was acquired by Carlton, which would eventually become part of ITV Plc; so it's likely the show has fallen into legal limbo.)
- Name's the Same: One of the contestants of the above-linked Win Elliot episode is named Dick Clark.
- No Budget: The NBC era's daytime set, which looked far cheaper and had a different layout than the upscale nighttime set. The UK version adapted this set for at least part of its run. Unfortunately, the nighttime version was also rigged, whereas the daytime version was not.
- Outlived Its Creator: The Martindale-Caldwell version continued for two years after the death of Jack Barry.
- What Could Have Been: There would have been a syndicated version no matter what, and it would have aired alongside the CBS version, when production began in June 1978. But when the daytime edition fizzled a month later, production immediately switched over to the syndicated edition. Tapings lasted at CBS Television City (using Studios 43 and 31) from June 1978 to December 1980 (two-thirds into season 3). Production then moved to KCOP-TV for all but the 1984-85 season (there, they were at The Production Group Center, as the KCOP studios were undergoing renovations). The 1990 version taped at Hollywood Center Studios.
