Just read his biography, and I'm kind of disappointed in him.
Coburn has always been my favorite actor since I was about 12. I used to watch all his old Westerns, War and Thriller movies on TV, having been too young during his initial popularity to see them at the movies.
Growing up without a dad around much of the time, I used to imagine that James Coburn was my dad, using him for a role model.
A biography was never available until recently, when his daughter-in-law wrote "Dervish Dust". It's a fascinating book about a complicated man, but I was saddened at how he neglected his kids.
He and his wife spent most of their free time jetting around the world, partying, smoking pot and pursuing faddish 1960s interests in Eastern beliefs, leaving their kids at home with nannies where they basically had to raise themselves. Coburn comes across in the book as very self-centered.
I still like his movies and he's still my favorite actor, but I now see what a flawed person he was in life.
