That’s a tough call. Arguably Ford could also have been drunk. People have had torrid secret affairs on movie productions since silent films even. Being in another country far from home on a long film shoot surrounded by a mostly British crew that could sometimes be hostile to the yanks in their midst is another factor. In that pre internet world one could easily feel cut off from home and family.
Does everything we love have to be tainted by the spectre of this now?
any one who took advantage of a drunk female could argue they were drunk as well.
