When I watched the TV show as a kid, Noel Neill was the real Lois Lane.  Phyllis Coates was the pretender.  But now, from a slightly older vantage point, I can see that while Phyllis Coates is quite a fine actress, Noel Neill....is not.
But, if you don't require much in the way of acting, Neill still looks like Lois.  To me, anyway.
