I guess Indiana Jones is old news now? Tough business!
I’ve always loved The Last Crusade, easily my second-favorite (after Raiders) of the films. But in 1989 I wasn’t particularly attentive to screenwriter credits (unlike composer credits).
This 2016 article from Creative Screenwriting (that I only saw recently) is a great look at the evolution of the Last Crusade script, the final version of which was by the playwright Tom Stoppard, uncredited.
Scripts are hard!
