Interestingly, Franz Josef added the second door (leading to the wraparound/lavatory/gangway) quite independently of Filmation's TAS. It's just a great coincidence that both chose the same location for another door.
What's your basis for that? FJ's manual and blueprints were published in 1975, just after TAS ended its run. They were evidently created during TAS's run. It stands to reason that FJ would've been influenced by the then-current screen incarnation of the series.
Well, the 1975 Manual is immaterial as the first FJ drawings to show the second door on the bridge were from the
Booklet of General Plans from 1973. FJ used the simple stardate format for all of his
Trek work, YYMM.DD and all of his drawings are dated. The sheet in BoGP showing the bridge (SHT 6 OF 12) is dated 7310.07, or October 7, 1973. "Beyond the Farthest Star' [TAS] aired on September 8, 1973, nearly a full month before the drawing was started. The first five episodes would have aired by then. So it is at least hypothetically possible that he saw an episode.
However, in interviews he claimed to not have ever seen TAS. The sources he used were mainly
The Making of Star Trek and various offerings from Franklin Mint, film frames mounted as slides and things of that nature. Given that the guy wasn't himself a
Star Trek fan and that he probably had better thing to do at 10:30 on Saturday mornings, I would not be surprised if he actually had not saw the show. Although, I will concede that, despite claims to the contrary, it is surely possible that his daughter of one of her friends had seen the cartoon show and suggested a second door at about that location (which, if you look, is close to but not quite in agreement with TAS).
So, an influence
may have crept in, there having been about a month's overlap between the airing of TAS and the illustration in question. But given that the parties involved have claimed that it didn't, and that no other TAS references exist anywhere else in FJ's work, I am lead to conclude that TAS was, in fact, not referenced by Franz Josef. His intent was to take the sets seen on the show and gently re-imagine them into something that he, as an actual engineer (a naval engineer at that, unless I'm very much mistaken) thought would make more sense. Check out his take on the Engineering Deck, or the Sickbay Facility. He took creative liberty with almost every part of the ship, including the Bridge, and I argue that the second door was his engineer's brain think, "hey, it's kinda stupid that the bridge has just the one door."
If you have evidence I have overlooked, I would be happy to be corrected.
