"The Return of the Archons" was the first appearance in
Star Trek for actor
Charles Macaulay. He later appeared as Jaris, prefect of Argelius II, in the second-season episode "
Wolf in the Fold". This was actor Jon Lormer's second appearance on
Star Trek. He had previously appeared as Dr. Theodore Haskins in the episode "
The Menagerie" and made a third appearance as an unnamed old man in the third-season episode "
For the World Is Hollow and I Have Touched the Sky". David L. Ross made his third appearance on
Star Trek in this episode, after having appeared as a security guard in the episodes "
Miri" and as a transporter chief in "
The Galileo Seven" earlier in the first season. He received his first speaking role as Lieutenant Johnson in the second season episode "
The Trouble with Tribbles", and appeared in another speaking role as Lt. Galloway in the second season episode "
The Omega Glory".
Character actor Sid Haig has a role as one of the hooded Lawgivers who first confront the landing party in Reger's boarding house. "The Return of the Archons" introduces for the first time the Federation's
Prime Directive. However, an important modification is made to the absolutist non-interference rule almost immediately. Kirk argues that the Prime Directive does not bar interference with other cultures, but rather bars interference only with a "living and growing" culture. Scholar Eric Greene argues this is reflective of the
"frontier myth" of
Star Trek and
American foreign policy in the late 20th century, in which a superior culture expands to impose its understanding of freedom and progress on others. M. Keith Booker, interpreting the politics of
Star Trek, agrees, noting that in leaving behind a sociological team to "help restore the planet's culture to a more human form" means restoring it to one that "suits the values of the Federation and twenty-third century Earth." Location shooting for "Return of the Archons" occurred on the
40 Acres backlot in
Culver City, California. The street scenes were part of the "Town of Atlanta", a set which consists of a mid-1800s city street, a town square, and a residential area (originally constructed for the motion picture
Gone with the Wind in 1939). The dungeon set was first constructed for this episode, and reused in the first-season episode "
Errand of Mercy" and the second-season episode "
Catspaw". Marplon's absorption booth console was also reused several times in the series. It reappeared (with modifications) as a relay station in the second-season episode "
I, Mudd", as a Federation outpost control panel in the third-season episode "
The Lights of Zetar", the housing for the Romulan cloaking device in the third-season episode "
The Enterprise Incident", and as the force field control station at the penal colony Elba II in the third-season episode "
Whom Gods Destroy". The computer that ruled Beta III was seen again (slightly modified) in the first-season episode "
A Taste of Armageddon". The doors to the Hall of Audiences were a re-use of doors previously seen in the episode "
What Are Little Girls Made Of?" and were reused in "A Taste of Armageddon". The episode contains two errors. When the "Festival" breaks out, the mob begins hurling stones at the landing party. A large "rock" made of
papier-mâché accidentally hits one of the
Enterprise security personnel in the head. The actor stayed in character and kept running to ensure that the
take was not ruined. When the landing party rests in a bedroom at Reger's boarding house, the windows are blacked out in all wide shots, but clearly transparent and showing the street outside in all close-ups. ==Reception==
