Before Demo Reel began, fans noticed that Rob always got the most fanservicey shots of Doug, whether it was him in the shower or just showing He Had Legs. So, in Transformers, Karl's camera being in love with Donnie gets lampshaded in the first five minutes.
Doug's characters have been shipped together since the dawn of fanfic writing, so that might be why Critic acts so seductively against Doug in The Review Must Go On.
Two SWAG members are voiced by Justin Carmical and Holly Christine Brown in episode 4. Brian Heinz plays Fabrizio, a recurring character, introduced in the same episode.
Also for episodes 4 & 5, the creepy girl who turns out to be in a family of obsessed Jimmy Boyd fans, is played by Briana Laws. She was the girl on the playground in Suburban Knights. Her parents, Jason, who was the moviemaker with the drill in To Boldly Flee, and Jori, play her character's parents in the latter episode.
Incestuous Casting: This was the show where Doug and Rob took their teasing Incest Subtext and turned it into in-character flirting. In one scene, Donnie actually asks Carl if he can join in on him having sex.
Old Shame: Not for Doug, but for Rob. While Doug had wanted to do it for five years and literally bounced every time he mentioned getting to create something new and dark, it was viewed by Rob as just something to do while getting the game show ready.
The Catwoman costume Rebecca wears in The Dark Knight Begins Rising (as Anne Hathaway's portrayal) is later reused when Rachel plays Michelle Pfeiffer in the Nostalgia CriticFilm/Catwoman review.
Real-Life Relative: The Fanatic Fan Family is played by the real-life Laws family, friends of Doug Walker who threw him a bone by co-hosting the Adventure Time Vlogs with him, in addition to having occasional cameos in other Channel Awesome productions.
Schedule Slip: Slightly. The second episode of Demo Reel missed a week because Doug Walker wanted to tweak the show's direction. The second episode ended up focusing more on the actual characters and put the parody scenes on the back burner. The 4th episode came after 3 weeks. On a grander scale, see above.
Screwed by the Network: Fans of the show got really pissed when the volume 4 TGWTG DVD advertisement came out, and we were told we wouldn't be getting any episodes (except the missing one) or commentaries, just bloopers.
The site's design (the redesign was "for real this time" promised in September but never happened) resulted in the show getting shunted to the "specials" section, along with Doug's obligatory Disney-movie-per-day series pushing any episode off the front page.
Throw It In: Happens everytime. Donnie keeps adding details to the script to justify their resources like "The character grew a goatee" or "One-glove Batman", and the list keeps getting bigger.
The actress rant in episode four was half written by the Walkers, half improvised by Rachel because of her own experiences in the industry.
The moonwalking in episode two and the "I speak cat" scene in episode one were also both improvised by Rachel. For the latter, speaking cat was actually the thing that got her the role in the first place, and Rob just asked her to do it again for the ep.
Trolling Actress: Doug won't say anything about anything, but Rachel likes to tease that the show will come back.
Troubled Production: There were a lot of problems with the studio they worked on, ranging from the humidity of the studio warping their sets to their difficulty in audio echo control to the props they had to work with.
There were a lot of computer issues while writing the script of the pilot and quite a few scenes were lost, which would explain why said episode was more comedic while the rest were far darker.
Type Casting: The sexist type is discussed. The two examples are Kathy Bates; psychos and smarmy bitches, and Meryl Streep; shrews, cartoons, cougars and MILFs.
Word Of Bi: Rob confirmed it for Donnie after the pilot note Doug would confirm it at Shadocon in the filming of his said-to-befavorite episode, when all he had done sexuality-hint wise was manipulate Tacoma with bedroom eyes. He'd go on to do much more.
What Could Have Been: Doug wanted Lewis and Lindsay on the show to play different people other than themselves or TGWTG characters, and prove again they could do drama.
As a Downer Ending as the show got, it could have been even worse. Brian wanted Fabrizio to return to the studios only to now find a completely abandoned warehouse.
Karl and Quinn would have assembled a team of film crew/mercencaries called "The Commendables" who would go on missions across the globe.
Doug mentioned in the A.I. commentary that he would've gotten around to having a TMZ-centric episode had the show continued. And due to his regret that the Critic episode was so cruel, and Demo Reel's A World Half Full optimism, it probably would have been Lighter and Softer than AI.
If Doug had the money for a studio, and the confidence and popularity for actors and an audience, the show could have aired in 2008. He'd been wanting to do it the entire time of Critic.
Writer Revolt: "All our hopes rest on the Nostalgia Critic. People will love that" was a clue of Reality Subtext. On the commentary, Doug talked about how even though he was given the choice to keep the show, Critic still had to come back to get the site back on good terms with money.
