James Coco, originally cast as Dog, couldn't 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, he suffered a gall bladder attack and eventually had to be replaced by George Cole. 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."

In an interview, director George Cukor recalled that during filming he received complaints from several English-speaking members of the Russian crew about star Jane Fonda. Their complaint was that instead of letting them do their jobs, she would follow them around quoting passages from Karl Marx and wanting to engage the technicians in discussions about them. They told Cukor they were already Communists, that Fonda didn't have to convert them, and if she persisted in her behavior the whole crew would go on strike. The producers spoke to Fonda and got her to stop.
