The casting is perhaps a bit of a surprise, since Lane is only 45 years old; most of the actresses cast as Martha Kent in previous films had proceeded well into senescence when the cameras started rolling. Eva Marie Saint was 82 when they shot Superman Returns, and Phyllis Thaxter was 57 in the original 1978 film. Even Annette O'Toole was pushing 50 when Smallville began production. Lane is only 18 years older than Henry Cavill, who'll be playing Clark Kent.
Still, Lane's a tremendously talented actress, and is always fun to watch on screen, even if she's been picking some relatively weak projects over the last half-decade, with movies like Untraceable and Killshot moving her career nowhere fast. Still, she was pretty effective as a mother in Secretariat, and I wouldn't be surprised if she's asked to turn in a similar performance in the upcoming Superman film.
