What makes this film fascinating is the conflict between the two characters, which is centered mostly on a great dialogue that explores the motivations and creative process of a genius, with Charlton Heston delivering
his typical overacting and Rex Harrison as magnetic as always.
There was potential for this film to be melodramatic and
overacted but I think, and this is
typical of a lot of Argentinian films I've seen, the films are believably acted and they have a grit to their visual style that is more realistic.
