IMAX 3D Theater 

Out with the dinosaurs, in with tornadoes: It's time for the periodic changing of the guard at the IMAX 3-D theater at the Denver Museum of Nature & Science. Replacing DinoMax, Born to Be Wild and Under the Sea are the 3-D, large-screen mindbenders Tornado Alley and Flying Monsters (okay, that's another dinosaur movie), which will both play several times a day at the theater in an open-ended run.

Tornado Alley, which follows Sean Casey of Storm Chasers and his fleet of customized vehicles equipped with high-tech gear and a 70mm camera, promises to be an edge-of-the-seat thriller. And David Attenbourough's Flying Monsters is certain to scare the living daylights out of you as it explores the rise and fall of the pterosaur, a little-known prehistoric flying beast with a forty-foot wing span. You know what IMAX does to even the most minuscule things; now imagine that with an airliner-sized winged reptile, in 3-D. Whoa.

The IMAX 3-D Theater, located on the second floor of the museum, at 2001 Colorado Boulevard, is open daily; for tickets, $6 to $10 (museum packages are also available), go to www.dmns.org/imax or call 303-322-7009. — By Susan Froyd
