Well, James Bond aside, the point is that no one version of a character is more "real" than any other. Bela Lugosi's version of Dracula is no more real than Christopher Lee's or Frank Langella's or Gary Oldman's or whomever. (We'll just forget about BLADE: TRINITY, okay?) Ditto for Sherlock Holmes, Tarzan, Zorro, Perry Mason, Nancy Drew, and, yes, James T. Kirk.
No character is off-limits to reinterpretation over time.
