Camp Kirby is an homage to the icon Jack Kirby, a writer, artist, and editor of comics. In 1957 he wrote and inked Green Arrow stories in World's Finest Comics and Adventure Comics, leaning more toward science-fiction than the Bat-Man clone the character had been at that point.

The ship that Oliver is incarcerated on in the flashback sequence is named Amazo. Amazo is the name of an android that was a frequent enemy of the Justice League (and has crossed paths with Green Arrow on occasion).
