The second pilot is more focused on action, features no self-doubting protagonist and fewer women. So Roddenberry's claims seem fairly consistent whereas you story about the studio wanting proof that the show could be done with a smaller budget seems fishy. Why not simply cut the budget, air the pilot and shoot the series instead of wasting an entire pilot? No, they obviously wanted an admittedly only slightly different product. And why do people care about Roddenberry's sex life?
