Bloody Sunday, a blistering re-creation of the Irish civil rights march in Derry three decades ago that left 13 unarmed civilians dead and 14 wounded, is the rare 2002 movie worth seeing twice. So take advantage of the chance to see it for the first time at an advance screening tomorrow night at 7:30 at the Charles Theatre, benefiting the Maryland Film Festival.

The movie is both a harrowing depiction of protest and repression and a heartfelt plea for finding negotiated solutions to bitter social-historical conflicts.

The hero (played by James Nesbitt) is an idealistic politician named Ivan Cooper. He's a member of Parliament, a civil-rights leader and a Protestant. Aptly enough, a politician will serve as host of tomorrow's screening and lead a discussion afterward: Baltimore Mayor Martin O'Malley.

Tickets for Bloody Sunday are $10. Call 410-752-8083. The Charles Theatre is at 1711 N. Charles St.
