Well, Seven, I had no problem with Lee, he was a drinking buddy... 
Clint, however, was another whole 'nother kettle of fish--
Not many folks know that the original screenplay for Paint Your Wagon was about "three" miners... 
that were married to Elizabeth--
However, when Jean Seberg fell in love with me because of my fabulous acting... 
and Broadway caliber singing, the green eyed monster came alive in Clint.
He had me banned from the set and the script re-written to exclude my character... 
Therefore, the film was a box office bomb when it came out.
Yet Clint apologized to me about a year later... 
and all is jake between us now.
