In his role for the magazine Ritterhouse would create several illustrations each month with a brief explanation or title to suggest material for the writers. The writers in turn would create stories relating to the pictures Ritterhouse created.
In 2374, Benjamin Sisko believed himself to be a writer for Incredible Tales named Benny Russell while under the influence of visions from the Prophets. In this capacity he took on the assignment of writing a story to accompany a picture Ritterhouse had drawn of a space station with a striking similarity to Deep Space 9. Benny couldn't quite understand why the picture felt familiar, but created a detailed story about the station and its crew. The entire magazine staff loved the story, and Ritterhouse in particular was impressed with Benny's descriptions of the Cardassians, especially their neck ridges. Ultimately, however, the story was not published in Incredible Tales due to its focus on a black captain amid the racism of the 1950s. (DS9: "Far Beyond the Stars")
Roy Ritterhouse was played by actor J.G. Hertzler, who usually portrayed Martok. Because Hertzler is actually an artist too, appearing as Ritterhouse was easy for him, even though he had never before appeared on Star Trek without wearing makeup. He said about playing the character, "[It] was like falling off a log for me [....] When I was sitting there drawing, I literally was drawing the cast." (Star Trek: Deep Space Nine Companion (p. 535)) Hertzler drew sketches of all the cast members, while they sat around the table.  Because he really is an illustrator, Hertzler "loved" portraying the artist Ritterhouse. (Cinefantastique, Vol. 32, Nos. 4/5, p. 100)
In the magazine Cinefantastique (Vol. 32, Nos. 4/5, p. 100), J.G. Hertzler alleged that, although the drawings shown on-screen as having been illustrated by Ritterhouse were produced especially for the episode and weren't done by Hertzler himself, he was able to keep some of the drawings he did during production on "Far Beyond the Stars". However, he also stated, in a later interview, that he hadn't really been allowed to keep those illustrations, commenting, "I returned those drawings to the prop department at end of show... and wish I had them now!"
