'Purple Rain' tonight, 'Sign O' the Times' Saturday

How often do you get to see two great Prince films on the big screen in one week in his hometown? The "psychobiographical" fiction known as Purple Rain screens tonight at 9:00 p.m. at the Regal Brookdale Center 20 theater (6420 Camden Ave N, Mpls., 763.566.3456). The classic and rarely screened concert film Sign O' the Times (here's Michaelangelo Matos's review) shows Saturday at midnight at the Uptown Theatre (2906 Hennepin Ave S, Mpls., 612.825.6006, official site here) as part of the Get Real City Pages Documentary Film Festival (Nov. 4-10). The entire Get Real schedule is live here, and in today's City Pages. The fest kicks off Friday at 2:30 p.m. with I.F. Stone's Weekly, a portrait of the independent journalist that couldn't be more timely in this era of media buyouts. Look for more recommendations here tomorrow.
