At a minimum, I saw Glynis Johns (three times), Jean Simmons, Blair Brown, Hayden Glynne (Boston), CZJ, BP, and Howes. IMO all were good, but none came close to Johns. I still think hers was the best Send in the Clowns, with BP also being truly memorable. I can picture Dench being great in the role, and have see her Clowns performance, which was among the best I have heard beyond the show, it I still stick with the beauty of Johns’ performance.
Given how mediocre the movie was, I would love to see a remake of some type. I think Renee Zellweger would be a great Desiree.
