From wikipedia...
"In 1943, [Jean] Rouverol and her husband had joined the American Communist Party.
In 1951, when agents for HUAC attempted to subpoena them, Rouverol and her husband chose self-exile to Mexico with their four small children rather than face a possible prison sentence, as endured by some of their friends who were dubbed the Hollywood Ten. Labeled as subversives and dangerous revolutionaries by the government, they did not return to the United States on a permanent basis for thirteen years, during which time they had two more children."
Ah, yep. I knew about all that. And I held back my inclination to sarcastically ask her “eh, real shame about the Soviet Union breaking up, huh?” I was really tempted! But, my deep affection and personal nostalgia for “It’s A Gift” (which I first saw on tv when I was in grade-school), kept me from opening that can of worms! Probably the only commie actor I’d bit my tongue for.
