All right, you caught us. There are only two IMAX theaters in Dallas, but each one has its advantages, its charm, its je ne sais quoi. While The Science Place generally sticks to more, uh, duh, scientific films, the Cinemark goes for the flash and hype. It's The Magic of Flight vs. Cirque du Soleil's Journey of Man, or Wolves vs. Siegfried and Roy. (If only that last match-up were real.) The Science Place has the huge, domed screen whereas Cinemark has a flat, rectangular screen like regular theaters, only with 3-D capabilities. The Science Place has that neat film of a helicopter tour of Dallas. Cinemark has traditional movie theater snacks. Both will end the year with a second run of Fantasia 2000.
