SNAFU, I think "Who is Batman to you" and "Who is Lois Lane to you" are interesting generational markers. As someone born in the late 1980s, who was a kid during the superlative "DC Animated Universe" of "Batman: the Animated Series" and "New Adventures of Superman," when I think Lois Lane I hear the voice of Dana Delaney, just as Kevin Conroy and Mark Hamill are Batman and the Joker to me. (Fans of animation and connoisseurs of voiceover artistry: was there ever a show as masterful as B:TAS?)
If I were ten years older, I'd say Michael Keaton would always be Batman to me, or that Dean Cain and Teri Hatcher were my Superman and Lois Lane.
