 James Coco (qv), originally cast as Dog, couldnt eat Russian  food; the only local fare he could stomach was bread and butter. He  wound up gaining so much weight his costume no longer fit, suffered  a gall bladder attack, and had to be replaced by George Cole (qv).  Coco later said, "They tell us [the movie] will finish by August,  but not by August of what year. I understand Elizabeth [Taylor] is  having Christmas cards printed."
