In the latest wrinkle in the journey of the highly controversial documentary Russians at War, the Security Service of Ukraine has reportedly opened a criminal investigation into Anastasia Trofimova, the film’s Russian-Canadian director.

“It’s troubling for me as a Canadian documentary filmmaker that there is an attempt to suppress my film through baseless and defamatory calls for investigations from both Ukraine and Canadian politicians and organizations,” Trofimova told the National Post on Thursday. “Not to mention the attempts to censor the selections of international film festivals.”
