This is the sort of movie that makes me ponder the whole time I'm watching it, "Who SHOULD have been in these roles?" Connery and Woodward really give it a good try, chewing big hunks out of the scenery, but they never convince, not for a moment. The role of earnest but ignorant and garrulous wife could have been played to perfection by Geraldine Page or, in an earlier and lighter version of the story, Judy Holliday. The role of Samson Shillitoe, deranged poet, could have been handled well by Jason Robards or Walter Matthau, and his mysterious attraction for women would have been more believable with the former, and more humorous with the latter.
For me, the only real laughs came from the one short scene featuring pudgy businessman Sorrell Booke learning the facts about his wife's hysteria. "You'll ascertain MY virility????"
I think they were trying for the kind of thing here where, like Alec Guiness's deranged artist character in "The Horse's Mouth," the obnoxious jerk has a mysteriously endearing charm or ability that shines through despite his appalling behaviour, but this poet isn't the horse's mouth. Quite the opposite.
If you enjoy the type of film that leaves you shaking your head and wondering why, this is definitely for you.
