For the book series
- Technology Marches On: You can tell how old the earlier books are by their lack of cell phones and their ilk. In the written-in-2005-and-2006 prequels, though...
"He also wanted to plead with her to watch the DVD [...] He had rewound it and left it in the VCR, hoping and praying she would watch it while he was gone."
- The updated version of the series updates the technology to later standards: VCRs become DVD players, CD players become iPods, cassette recorders become MP3 recorders, etc.
- A telling moment of this is in Chapter 12 of the first book, which mentions a video recording of a sermon about the Rapture that Rayford has watched. Apparently, the rewrite missed a pretty crucial use of the word "VCR":
- The Danza: Kirk Cameron playing Cameron "Buck" Williams.
- Subversion; Williams was named well before Kirk Cameron got the part, since the book came out well before the movie.
- Dawson Casting: In the first Left Behind film (which came out in 2000), Chelsea Noble was in her mid-thirties, playing 27-year-old Hattie Durham. Janaya Stephens was 27-years-old at the time, playing 20-year-old Chloe Steele. Gordon Currie was also in his mid-thirties at the time, playing 33-year-old Nicolae Carpathia. Played almost straight with Brad Johnson, who was 41-years-old playing 42-year-old Rayford Steele. Dead-on with Kirk Cameron, who was 30 at the time playing Buck Williams, also 30 years of age.
- Disowned Adaptation: Tim LaHaye and Jerry B. Jenkins, the authors of the Left Behind series, hated the adaptations by Cloud Ten Pictures, calling them "church basement movies" and going so far as to sue the studio (and win) over it. As a result, their names are not listed in the opening credits of the first film, even though it still lists the novel as the source material. This is a big part of the reason why the film series was rebooted.
- The Other Darrin: In the first two movies, Bruce Barnes was played by Clarence Gilyard, Jr., before being replaced by Arnold Pinnock.
- Due to scheduling conflicts, Gilyard was unable to reprise his role as Bruce in the third movie. That and since Gilyard is a Roman Catholic, his priest was slightly peeved about him taking the role, given the series' stance on premillennial rapturist theology, and was very happy when Gilyard did not reprise the role.
- Real-Life Relative: Inverted, as Kirk Cameron (Buck Williams) and Chelsea Noble (Hattie Durham) are married in real life, having met on the set of Growing Pains.
- Ironically, Kirk Cameron admitted that his wife had pictured a movie adaptation in her mind with the both of them as Buck and Hattie respectively shortly after completing the first book. Several weeks later, Cameron was notified of the movie adaptation and was tapped for the role of Buck Williams. He got the part of Buck, while Chelsea Noble claimed the role of Hattie.
- Wag the Director: As mentioned on the trope page, Kirk Cameron did not grow out of this after Growing Pains. In Left Behind: Tribulation Force, there's a scene which has Buck Williams (Kirk's character) and Rayford Steele confronting a friend of the latter who didn't want to hear what the Antichrist planned to do. Cameron (who by that point had just teamed up with Ray Comfort's "The Way of the Master" ministry) manages to combine this with a Big Lipped Alligator Moment when he suddenly throws in this random string of questions related to the 10 Commandments lifted almost word for word from a "The Way of the Master" video he appeared in.
- What Could Have Been: Lacey Chabert had been considered for the role of Chloe Steele before dropping out due to scheduling conflicts.
For the 2014 film
- Box Office Bomb: Budget, $16 million. Box office, $21,106,062.
- Creator-Preferred Adaptation: LaHaye and Jenkins both gave the 2014 version high marks, with LaHaye even describing it as "the best movie ever made about the Rapture".
- Stillborn Franchise: From the looks of it. The ending of the film obviously sets up for a sequel and the creators started pitching for one on Indiegogo in April of 2015, hoping for a release in the summer of 2016. However, by the time the crowdfunding campaign ended a month later, it hadn't come close to its $500,000 goal. The film's website hasn't been updated since, leaving the future of the film unclear.
