* CaliforniaDoubling: {{Averted}}, since it's set in California. However, Seaview Circle is based on Crystalaire Place, a real cul-de-sac in the Granada Hills area of Los Angeles. Knots Landing is depicted as being near a beach. Granada Hills is actually on the north side of the San Fernando Valley, 25 road miles from the nearest beach.
** If you look for Crystalaire Place in a map program, you'll see almost the exact same houses there, just like if you look for Southfork in Dallas.
* {{Fan Nickname}}: Poor Val.
* {{I Want You To Meet An Old Friend Of Mine}}: In all but his first ''Knots Landing'' appearance as J.R., Larry Hagman was reunited with his ''The Good Life'' co-star Donna Mills (Abby). They played a married couple, Albert and Jane Miller, in ''The Good Life'' and in-laws in ''Knots Landing'' as Abby later married J.R.'s brother Gary.
* KeepCirculatingTheTapes: As noted in the intro, it's not available online, and only the first two seasons have seen official DVD release.
** Every episode of Seasons Three to Fourteen is now available online, through different sources and in varying quality, if you look very, very hard.
* {{The Other Darrin}}: A minor example. Allan Miller played Laura's flirtatious boss Scooter Warren in two episodes of Season Two before being replaced by John Considine in the later second season episode "More Than Friends". {{The Original Darrin}} Allan Miller returned to the role in five episodes of Season Three, meaning that he was presumably just unavailable during the filming of "More Than Friends". Miller and Considine do vaguely resemble each other but the switch and switch back of actors was made more obvious by the fact that Miller was clean shaven while Considine had a moustache.
* {{Playing Against Type}}: Considering that Donna Mills had become known for playing victims for much of the 1970s, her being cast as the manipulative Abby certainly qualifies.
* {{Real Life Relative}}: Joshua Devane plays the younger version of his father William Devane's character Greg Sumner in nine episodes from 1986 to 1990.
** Constance McCashin's husband Sam Weisman played David Souther, a client of Laura's who wanted to have an affair with her, in the Season Two episode "A State of Mind".

** To viewers of both ''Dallas'' and ''Knots Landing''
*** Priscilla Pointer played Beatrice Handleman in the ''Knots Landing'' Season One episode "The Constant Companion" and was later cast as Cliff and Pam's mother Rebecca Wentworth in ''Dallas''.
*** Don Starr played the oil man Jordan Lee in ''Dallas'' from 1978 to 1990, appearing in all but the first season. Early in his ''Dallas'' run, he played Judge Murphy in the ''Knots Landing'' second season premiere "Hitchhike".
*** Similarly, Tom Fuccello played Donna's stepson Senator Dave Culver in ''Dallas'' from 1979 to 1991 and appeared as a different character in a ''Knots Landing'' episode early in his ''Dallas'' run. He played Ed Kroft, another politician, in the Season Two episode "Kristin".
*** Barry Jenner played Abby's ex-husband Jeff Cunningham in ''Knots Landing'' Seasons Two and Three and later played Dr. Jerry Kenderson, Mark Graison's best friend and Sue Ellen's Dream Season lover, in ''Dallas'' Seasons Seven to Nine.
*** {{The Other Darrin}} David Ackroyd, who played Gary in his first appearance in the ''Dallas'' second season two-part premiere "Reunion", played Bill Medford in the ''Knots Landing'' episode "Mistaken Motives". He even shares a scene with his successor Ted Shackelford at one point. Ackroyd reportedly turned down the opportunity to reprise his role as Gary as he did not want to do a series. Considering Shackelford got 14 years of work out of ''Knots Landing'', you have to wonder if Ackroyd regretted that decision.
*** Allan Miller played Scooter Warren in ''Knots Landing'' Seasons Two and Three from 1980 to 1982 and later played Frederick Hoskins, the assistant district attorney who prosecutes Jenna for the murder of her first husband Renaldo Marchetta, in ''Dallas'' Season Eight in 1985.

*** K. Callan played Ciji's mother Mrs. Dunne in the ''Knots Landing'' Season Four episode "The Fatal Blow" in 1983 and later played April and Michelle's mother Amy Stevens in four episodes of ''Dallas'' Season Thirteen in 1990.
