Actually, his/their daughters asked Ethan Hawke to make this documentary and are interviewed/contributed throughout. I think they did this to get ahead of a biography coming out about Paul Newman that is supposedly not very flattering.
Richard Harris was a great actor. I found out when he stated that Newman(and Redford) “were not actors”. Made me think. He stated the two of them played ‘characters’. I could not picture Newman playing Cromwell like Harris did. Made me appreciate Harris more as I realized Newman and Redford got by a lot on their looks. Cruise? I dunno.
