Christopher Vourlias Several leading Ukrainian filmmakers have called out the Karlovy Vary International Film Festival for including a Russian film in its 56th edition, which kicks off on Friday, insisting that it’s reneged on a promise not to welcome any movies with ties to the Russian government.In a letter addressed to artistic director Karel Och and festival leadership that was shared with Variety, the filmmakers behind Dmytro Sukholytkyy-Sobchuk’s “Pamfir,” Maksym Nakonechnyi’s “Butterfly Vision” and Valentyn Vasyanovych’s “Reflection,” criticized the long-running Czech festival for including “Captain Volkonogov Escaped,” by directors Natasha Merkulova and Aleksey Chupov, in its Horizons sidebar.
