De Palma
In the documentary "De Palma", the director indicated that he felt the major flaw of the film was in casting Cliff Robertson. De Palma felt that Robertson couldn't play the anguish of the character, and was frequently difficult on-set. De Palma was effusive in his praise of Bujold who he felt had the more difficult role, which she played admirably, giving the film the emotional resonance needed for the project.
