Will Tizard ContributorWhen Liev Schreiber first encountered how ordinary Ukrainians on the ground are handling the vast and urgent crises brought on by the Russian war, he says, one thing was clear to him immediately: “They were doing all the work.”Speaking about his non-profit BlueCheck Ukraine at the Karlovy Vary Film Festival on Saturday, the actor/writer/producer explained this realization is central to his newly organized efforts to help.Schreiber was also motivated to found BlueCheck Ukraine after hearing many Americans express doubt about whether funds donated to the war relief effort would reach those most in need. Westerners are skeptical about transparency in Eastern Europe, he learned, likely because of the region’s history of corruption and waste.
