The interrogating officer has loose helmet straps when he's interrogating Burns, but when the camera pans from him to his reflection in the one-way mirror, the helmet has no straps, fastened or loose.
The taped replay of the Flash arguing with the director is off - first of all the shot is over the director's right shoulder, but the only camera originally present was at right angles to him and Flash. Also the sequence of events on the tape is different - the director goes flying and the set walls fall down much faster.
When the military man drives onto the base, he'd holding the wheel tight with both hands - where's the gemstone? It presumably has to touch skin, so it might be beneath his shirt or something...but then how'd it go flying when he crashed?
You only salute in the American military when making a report to a superior officer or when on duty as a guard - neither of these apply when the general simply walks into what appears to be a lounge, but everyone salutes him anyway.
Wonder Woman: And what's wrong with the way I dress?!?
Flash: (to GL) Uh...you wanna take that?
Wonder Woman: You slimy little weasel – do you think I can be bought and sold?
Artie: A tough negotiator – I like that.
Flash: Hey, we should take a road trip!
Green Lantern: What?
Flash: Think about it - two hard-traveling heroes cruising the countryside looking for America.
Green Lantern: Uh, yeah, I'll let you know when my schedule frees up.
Godfrey: Maybe you'd care to explain why on your watch, 50% of marriages now end in divorce, and the other 50% end in death!
Green Lantern: Why do you need a van? Wait, don't answer that - I don't want to know.
Godfrey: Role models? Look, I've seen showgirls with more modesty then this so-called Wonder Woman.
Flash: This bites! Your commercial's stupid, you're a no-talent hack, and your donuts are stale! I'm outta here fast, Fast, FAST!
The music which can be heard after Flash confronts the talkshow host, Glorious Godfrey, is the same which can be heard in Teen Titans episode "Car Trouble," when Cyborg repairs the T-Car in the beginning and in the end of that episode.
Character bios: Eclipso, Glorious Godfrey
The night this episode first aired, there was a lunar eclipse in real life.
When Cartoon Network premiered this episode, they aired the two episodes back-to-back, without inserting closing credits at the end of part one or opening credits/recap at the beginning of part 2. They still listed the title and writer/director credits, though.
The soldier who tells the first possessed soldier to "Don't move!" sounds suspiciously like Kevin Conroy (Batman).
Flash Rogues Gallery villains Heat Wave, Captain Boomerang, and Mirror Master (unnamed here) all appear in the opening commercial. It's not clear if they actually are villains are just made up for the commercial.
The two cops questioning General McCormick are the same cops who interrogated Flash in "The Brave and the Bold".
Only Green Lantern, Flash, and Wonder Woman appear in this episode.
Alluding to the Green Lantern/Green Arrow road trip in Green Lantern #76-89 (first series), written by Denny O'Neil and penciled by Neal Adams. Note that Flash describes them as potential "hard traveling heroes" - the title of the trade paperbacks they were assembled in was "Hard-Traveling Heroes".
The Innocent Seduced' by Dr. Frederick
Alluding to the book Seduction of the Innocent, by Dr. Fredric Wertham, who wrote a book in 1954 linking anti-social violence to comic books.
Chung: Actually, I'm here to keep the world safe from warlords and petty dictators like Fassan.
Fassan sounds a lot like Saddam -- Saddam Hussein, the ruthless dictator that ruled Iraq since 1979.
General: Instead of shooting down nuclear missiles in space...
This refers to the Strategic Defense Initiative (SDI) proposed by President Ronald Reagan in the 1980s. The SDI was suppose to shoot down incoming ICBMs. Dubbed "Star Wars" by the mocking commentators, the SDI did contribute to bringing the Soviets to the bargaining table. Today the SDI is becoming more and more a reality as deployment is being sped up for june of this year according to news reports. On a side note: the Watchtower itself could be seen a step in the "weaponization" of space. For an interesting read on how powerful a moon base can be in war read The Moon is a Harsh Mistress.
