This week we lost Margot Kidder, taken too early at the age of 69.
A troubled soul, with a rich acting resumé during the '70s and '80s, for many of us she will always be remembered as Lois Lane in the Christopher Reeve-fronted Superman movies.
To me (and many others), she is the definitive Lois Lane. I was transfixed by her screen presence as the tough investigative journalist for The Daily Planet, and Lois and Margot - in my mind - were one and the same.
The pairing of Reeve and Kidder was lightning-in-a-bottle movie magic.
Whatever you may think about the scripts or the dated special effects of those films, the reality-altering alchemy of great movie-making allowed the iconic Superman and Lois Lane to step straight from the pages of DC Comics onto the silver screen (and ultimately into our homes) in the form of Christopher Reeve and Margot Kidder.
This once-in-a-lifetime cinematic sorcery has never been repeated, and probably never will.
As with the tragic passing of Carrie Fisher, my geek heart is broken once more.
Of course, I didn't know Margot - any more than I knew Carrie - but that doesn't stop these actors (and, just as importantly, the roles they played on screen) from being key parts of my emotional and spiritual development.
Margot's Lois Lane is as responsible for my tentative early steps into journalism as Christopher Reeve's Clark Kent.
My heart goes out to her family and friends.
RIP Margot Kidder (17/10/1948 - 13/5/2018)
