If you've had enough of all that late-night poker playing on NBC, how about watching what Hollywood can do with a standard 52-card deck? 21, starring Kevin Spacey as a university professor who recruits six MIT students to count cards for him in Las Vegas, gets a free screening Saturday at the Enoch Pratt Free Library, 400 Cathedral St. The 2008 film, directed by Robert Luketic (Legally Blonde), also stars Kate Bosworth, Laurence Fishburne and Jim Sturgess. Showtime is 2 p.m. in the library's Wheeler Auditorium. And if you like the movie, here's a bonus: Author Ben Mezrich, on whose work the film is based, will be at the Pratt at 6:30 p.m. Tuesday to talk about his new book on the founding of Facebook, The Accidental Billionaires. Information on both events: prattlibrary.org/events or 410-396-5430.
'Rashomon' : With the auction of the Senator Theatre scheduled Wednesday morning, owner Tom Kiefaber continues to celebrate his family's 70-year run as custodians with some great revivals. Beginning today, a beautifully restored print of Akira Kurosawa's 1950 Rashomon, a rumination on the nature and elusiveness of truth in which a rape and murder in feudal Japan is recounted from four widely different points of view, is scheduled to play the historic theater.
