A Day on the Force @ Siskel Film Center

If you missed last year's film A Day on the Force: Women's Professional Tackle Football when it was screened in June, you have a second chance to catch it tonight at 8:15 at the Siskel Film Center. The film follows the Chicago Force football team through their inaugural season in the new Independent Women's Football League. Even if you've seen it already, the film has been updated and re-edited, so you might want to check it out again. Co-director Ronit Bazalel, members of the Chicago Force, and other members of the film crew will be on hand to discuss the film. If you can't make tonight's screening, the film will also be shown on Sunday, May 2 at 5:00. Siskel Film Center: 164 N. State. (312) 846-2600.

The festival runs through May 9th, and features various groups from Chicago and abroad. The hot ticket is probably Friday, May 7th, as the LA group Totally Looped (featuring Oak Park, IL, native Dan Castellaneta) takes the stage to add new dialogue to old film clips (LA Connection, do I hear someone say?). Tickets are available through Ticketmaster and at the Athenaeum box office.
