OCA TURNS THE BIG 2-0: If you are a fan of arts and culture in Dallas, you have the Office of Cultural Affiars to thank for helping to string together many of the events you’ve attended over the last 20 years. The recent Free Night of Theater promotion is just one of the programs that the OCA has made happen. April 12 marks the 20th anniversary of the day that the city council approved the ordinance that created the OCA, and the OCA has a lot of celebrating planned. The main program is called “20 Days, 20 Deals: Celebrating 20 Years of Excellence in Dallas Arts and Culture.” From April 13 to May 8, you can go to the OCA’s Web site for info on discounts to area cultural events.

SHAKE HANDS WITH WOLVERINE: We’re about a month away from the start of the summer movie season, and with those big movies comes big movie promotions. This one actually sounds kinda cool, though. 20th Century Fox is holding a contest to stage the premiere of X-Men Origins: Wolverine in your hometown. Wolverine himself, Hugh Jackman, made the announcement yesterday in a YouTube video. All you have to do to participate is visit the film’s Web site and drop an X on the place you want the premiere to be held. DFW is a pretty big media market, so I suppose there is a chance it comes here on April 27. But it goes without saying that New York and L.A. probably have a pretty good shot. Still, part of me holds out hope that one of those Internet campaigns gets going to build support for having it in some tiny town in Alaska or something. I’m not holding my breath, though. If the premiere doesn’t come here, don’t worry — you only have to wait a few more days for its May 1 release.
