Note

• Tra i possibili interpreti di Spock era stato contattato anche Martin Landau (il comandante Koenig di Space:1999), che ha rifiutato perché ha ritenuto che l'impedimento di mostrare emozioni sia limitativo per un attore.
• Il secondo nome di Spock non è pronunciabile, come dice Spock stesso in This Side of Paradise. Secondo l'Officer's Manual (probabilmente per un'idea di Dorothy Fontana) il secondo nome di Spock è Xtmprszntwlfd, pronunciato in sei sillabe. Nel romanzo Ishmael di Barbara Hambly si dice che il secondo nome di Spock è S'chin T'gai.
