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.
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.
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.
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.
