I get that, at the time, Lucas and Spielberg thought of Indiana Jones as a sort of American James Bond, and having a different beautiful woman in every film was just part of that formula. But even as a kid, I was disappointed that Marion wasn’t in the second and third movies. Willie and Elsa weren’t half as good in my opinion.
There are rumors that Disney will try to reboot the Indiana Jones movies. If that happens, I hope they Keep Marion around. Or, failing that, if they made a series of films for their streaming service of Marion’s adventures on her own before or after Raiders of the Lost Ark, I’d watch them. An American woman in the 1930s doesn’t end up owning a bar in Nepal without there being a good story attached.
