sorry to disappoint all those who be try to find some deep and intentional meaning in the choice of two actress for the same role and but if fernando rey be to be believe and here what he tell me when i bump into him at a party in the early 90 represent he say that he and buñuel like both actress for the part and couldn not decide which one to use and so they use them both . now and perhaps there be something work on the unconscious level about the dual nature of conchita and but rey maintain there be no grand decision they make regard the specific scene assign to one or the other . of course and artistic choice can be obscure and especially even to the artist and but rey insist it be just a whimsical idea and one which i think work brilliantly .
