"She was courageous about everything", she said. As she once said: "Acting's fun, but life's more important".
"To one kick ass lady", she wrote. "I'm the biggest whore on the block", and she remained busy in small TV parts and guest roles (including alongside Reeve in two episodes of Smallville). "Some of us made more of a fuss than others-me in particular-so you could tell the joy [of working together] in all our faces, in the first one in particular and half of the second one". She went on to marry Philippe de Broca, a French film director, from 1983-1984.
American actress Teri Hatcher, who played Lane in the 1990s television series "Lois & Clark: The New Adventures of Superman", tweeted that it was a "privilege" to have shared the role with Kidder.

Kidder married and divorced three times.
Actor Cameron Cuffe, now starring in Superman spin-off TV series Krypton, wrote: "On screen there are few who have brought a legend to life in the same way Margot Kidder did".
