What I do know is, from a "First Contact" point of view, it doesn't get any better than when the Vulcan survey ship T'Plana-Hath sets down and, when Cochrane figures out he cannot return the Vulcan greeting, does a mental "Ahhh...Fuck It" and extends his hand. You can "see" Cromwell doing it!!!
And, again, as the camera pulls back, when Senet/Solkar (Cully Fredrecksen) has been seated inside Cochrane's tent and "Ooby Dooby" suddenly comes on very loudly you can see Senet, alarmed, half-stands before Cochrane reassures him with a gentle hand on his shoulder.
Fucking. Premium. Acting.
You have 2 names here, "Senet/Solkar". The Vulcan who first came out of the T'Plana-Hoth and greeted Cochrane. Was the character listed as both names in the credits? Point of interest, wasn't Solkar the name of Sarek's grandfather? (From Search for Spock, "Sarek, child of Skon, child of Solkar).
The Vulcans greeting Cochrane is among my favorite parts of the movie.
Solkar (yes, that Solkar) is the name given to the Vulcan captain in Decipher's Star Trek Card Game, and since adopted to the character in many novels, RPGs, and reference works. Enterprise revealed that Solkar was the first Vulcan Ambassador to Earth, which is kind of an odd career leap for a survey ship captain.
Cully Fredrickson preferred the name "Senet" for his unnamed character, but as far as I'm aware, that never appeared anywhere outside of fandom.
