Well... it was the last production that Jack Warner was personally supervising and you could tell he was eager to retire.
What I find with many of staggering sixties elephants is that the parts are better than the whole. Nobody would consider Dr. Doolittle or Chitty Chitty Bang Bang classics, but they all had jaw-dropping moments that just demanded a second viewing. I can help it. I start sobbing when Rex Harrison sings to Sophie the seal.
Technically, the last he personally supervised was 1776, for Columbia. The odd thing about CAMELOT, is that Jack Warner was committed to doing the film with the original cast;or, as much of the original cast he could get. Richard Burton, Julie Andrews and Robert Goulet were all offered the film. When Burton declined, and Julie Andrews declined because she wasn't interested, without him, Warner tried to sway her with all sorts of promises (the highest salary in history, director approval, percentage of the box-office, etc.), she still declined, famously stating, "I'll play a supporting role to Richard Burton, but never to Richard Harris." She and Harris were not fans of each other, during their time on HAWAII. Logan did not want her, but had she signed on, she probably would have replaced him, anyway. Redgrave said, when asked by a reporter how she felt about securing a role from the Number 1 box-office star, Julie Andrews, "I've no doubt she would be playing this role,if she wanted it." So, as much as Warner was lambasted over his MY FAIR LADY casting, he couldn't redeem himself with CAMELOT. He would do this, mostly, with 1776.
