Chicago-based critic and essayist Ignatiy Vishnevetsky has been named co-host of "Roger Ebert Presents At the Movies." He replaces Elvis Mitchell, who left the show several weeks ago. Vishnevetsy will join Associated Press movie critic Christy Lemire on the new movie review show slated to debut on WTTW-Channel 11 in Chicago and public television stations nationwide on Jan. 21.

Vishnevetsky, 24, is a critic and essayist for Mubi.com, a new multinational streaming site that bills itself as an online cinematheque. Vishnevetsky also is a co-founder of Cine-File.info, which tracks alternative cinema in the Chicago area, and he helps program the Cine-File Selects series at the University of Chicago's Doc Films, the nation's oldest film society. In addition, he contributes to the Chicago Reader.

Prior to becoming a film critic, Vishnevetsky, who is multi-lingual, worked as a translator for Novoe Literaturnoe Obozrenie, a literary journal in Russia.

Born in the Soviet Union, Vishnevetsky moved to the United States when he was eight. He went to high school in Milwaukee, but moved to Chicago after graduating,
