• Alex Ross Perry and Carlen Altman in The Color Wheel

The 24th Onion City Experimental Film and Video Festival opened last night at Gene Siskel Film Center, but there are still plenty of programs to come tonight and tomorrow at Columbia College Ludington Building, 1104 S. Wabash. Ben Sachs has a roundup of the festival’s best offerings in this week’s movie section, and you can see a complete schedule here. Also in this week’s issue, we recommend Alex Ross Perry’s black-and-white indie The Color Wheel, which took the prize for best narrative feature at last year’s Chicago Underground Film Festival and returns to Chicago for a weeklong run at Facets Cinematheque.
