This weekend, the N.C. Museum of Natural Sciences will add a new dimension to its high-definition theater. Needless to say, that dimension will require special glasses.

Starting on Saturday, the theater will begin showing Tornado Alley in 3-D. The 20-minute film documents storm chasers on a dangerous, tornado-tracking mission; star and director Sean Casey (who appears on the Discovery Channel reality show Storm Chasers) will attend, along with the reinforced Tornado Intercept Vehicle (TIV) that he drives in the movie.

But, of course, the big story is the inclusion of a digital 3-D projection system in the theaterโ€™s projection booth. According to the museum, discussions of including a 3-D system began earlier this year when Capitol Broadcasting CEO Jim Goodmon (whose station, WRAL, sponsors the theater) suggested that itโ€™s time 3-D films played there. WRAL VP/ general manager Steve Hammel says 3-D films were the next logical step in the theaterโ€™s evolution. After all, the museum prides itself on being one of the first facilities in the state to have an auditorium with a high-definition projection system.

โ€œBut itโ€™s really for the experience that people have as they go through the museum, to really see nature at its finestfirst in high-definition and, now, in high-definition 3-D,โ€ says Hammel.

Along with its regular 2-D projector, the theater will now be equipped with a Barco DP2K-20C compact DLP projector, which will show films in Dolby Digital 3D. Next to the Southpoint Cinemas in Durham, this will be the second spot in the Triangle to show films in that format. And just like at Southpoint, audiences can see the films with plastic 3-D glasses.

Unlike previous films that were screened at the theater, Tornado Alley comes with a price tag. Adults can check it out for $4, while kids from 2 to 11 have to cough up $3. Museum โ€œfriendsโ€ shell out $2. Greg Snyder, the museumโ€™s interactive multimedia design analyst (translation: He handles the A/V), says that this is โ€œan opportunity for us to get some revenue and to show some technologyโ€ at the museum. But he also feels that audiences will be stepping into a new realm once they view movies there.

โ€œIt gives you more of a feel,โ€ says Snyder. โ€œLike, when you see the movie, when youโ€™re in the tornado, youโ€™re gonna feel stuff.โ€

While the digital 3-D is a nice perk, the widescreen, 260-seat theater doesnโ€™t have a giant screen (like that other downtown Raleigh museum with the big-name 3-D theaterMarbles, for you newbies) that could envelop audiences in the experience. (Tornado Alley was legitimately made for giant-screen theaters.) However, the auditorium is equipped with a 7.1 Dolby Digital surround-sound system, which makes everything sound like youโ€™re in a tornado.

Nevertheless, both WRAL and the museum sound psyched that theyโ€™re offering the 3-D experienceif, for nothing else, but to give attendees something extra.

โ€œThereโ€™s really no reason [for the museum to do this] other than having a great experience for people in our community to enjoy nature as if itโ€™s right there in front of them,โ€ says Hammel. โ€œThatโ€™s what this does.โ€
