At the end of “Superman II,” Kidder played maybe her finest scene where she admits her own lack of character to Reeve’s Clark Kent. “I am selfish when it comes to you,” she says, her eyes tearing up and her very thin face drawn as if by illness. “And I’m jealous of the whole world.” Can you remember her low voice saying those lines? The emotion in that scene is very raw and very personal. It showed once again that Kidder was willing to put herself on the line, just as she had in “Sisters.”

Kidder had some control over her career for about ten years after the first two “Superman” movies, and she did some ambitious things, like filming the plays “Bus Stop” and “Pygmalion,” where she played Eliza Doolittle to Peter O’Toole’s Henry Higgins. She was the adored woman in a three-way love affair in Paul Mazursky’s “Willie & Phil” (1980), and she was at her very best as the freakish, outcast Rita in “Heartaches” (1981), a performance that earned a very admiring review from Pauline Kael. She played a Southern belle in the epic “Louisiana” (1984) for TV, where she was directed by one of her husbands, Philippe de Broca.

After that? Well, there was lots of work, and lots of personal trouble in the 1990s. Kidder kept going and going, and she was open about admitting that she would accept just about any offer of acting work in this new century. Kidder collaborated with Charles Burnett on the little-seen “The Annihilation of Fish” (1999), but most of her later credits were not worthy beyond the paycheck they afforded her. Kidder was a very outspoken political activist to the end, and she found ways to live as rich a life as possible and not take what was left of her acting career too seriously.

I was very wounded when I heard that Kidder had died because I never got the chance to tell her how much I loved her in “Superman” and how much her performances in the first two movies meant to me as a child. She had such chemistry with the very square Reeve because she was such a feisty, un-appeasable presence. Kidder posed for cheesecake photos when she was young, but it seemed clear that she had other things on her very active mind.

Kidder led a turbulent life. But think of her in that blue dress interviewing Superman on the terrace of her apartment in the first “Superman” movie, and the way she looks at Reeve, as if she can’t believe in his purity, and then watch the way she begins to melt and accept that she has met the ideal man, with the catch that she can never settle down with him.

Kidder’s own tumultuous spirit seems to finally settle down a little in this scene, and the effect is very touching because she’s smart enough to know all the trouble she’s in for with this superhero but game enough to enjoy the ride with him, even the rough patches. In that way, Kidder’s Lois Lane is close to the spirit of the troublemaking woman who played her so memorably.
