I looked a little sideways at Shatner's Movie Memories when he described meeting Armstrong, Aldrin, and Collins in the summer of 1968 and they were being touted as "the guys that were going to land on the moon". My understanding was that no one knew any such thing in 1968. They knew they were going to be Apollo 11, but NASA also expected that there would be repeat missions and schedule changes.
Actually up to April 1968 (according to
Deke!, by Deke Slayton and Michael Cassutt, and one of the best possible references for crew assignment planning in that era since Slayton made the schedules from Gemini through Apollo-Soyuz), Michael Collins was assigned to Apollo
9, alongside Frank Borman and Bill Anders. The backup Apollo 9 crew -- and thus the Apollo
12 heirs presumptive were Neil Armstrong, Buzz Aldrin, and Jim Lovell. Then Collins had to go into surgery for a bone spur between two vertebrae, and Lovell was moved up to the prime crew of Apollo 9, with Fred Haise taking Lovell's spot on the backup crew/Apollo 12 designate.
In August 1968, since there was little hope that the Lunar Module to be tested in Earth orbit planned for what was then Apollo 8 -- with crew Jim McDivitt, Dave Scott, and Rusty Schweickart, and backup crew (thus Apollo 11 likelies) Pete Conrad, Richard Gordon, and Al Bean -- Frank Borman accepted the plan to change his Apollo 9, a high earth orbit Command/Service and Lunar Module test, into a lunar orbit Command/Service Module test, with the schedule swapped to come ahead of McDivitt's crew.
So that's when Borman, Lovell, and Anders became the crew of Apollo 8, and the presumptive Apollo 11 crew became Armstrong, Aldrin, and Haise. Collins, recovered from surgery, was given the formal assignment to Apollo 11 after the return of Apollo 8, and Haise became the Lunar Module pilot backup for 11, with the schedule to fly on 14. (Apollo 13 and 14 had a switch too.)
In short, through 1968, Armstrong-Aldrin-Collins weren't a team, although there was good reason to expect that Armstrong or Conrad would be prime candidates for first-on-the-moon, and Aldrin or Bean would be with him.
(There was also a bit of a complicating factor that Slayton was willing to throw the schedule overboard if he had good reason. He would have made Grissom the commander for the first landing were Grissom alive whatever the rotation ended up doing if it were not an obviously impossible choice -- such as being vetoed by a higher-up, or had Grissom flown much too recently to be able to train for the landing mission -- and he considered offering it to Borman.)
Of course, it's worth remembering first that any group of astronauts shown to the
Star Trek people around that time could be fairly well described as ``the people who are going to walk on the moon'', and that it would be natural if one met Armstrong or Aldrin before Apollo 11 to remember them with singular interest afterwards. Most people would do the same.
