'Iron Man 3' is going to play in 4DX format in Nagoya, Japan, beginning on April 26.
According to The Hollywood Reporter, 4DX includes extras such as "strobe lights and equipment in the ceiling that can drop bubbles down upon the audience."
The 4DX format requires a theater to be specially constructed to create special effects, which correspond to what is happening on the film, says Wikipedia.org.
To accomplish this, the 4XD track is added to the film to trigger special effects such as seat motion, vibration, air jets, mist, lighting effects, smoke and even aromatic vapors.
The Nagoya, Japan theater is owned by Korona World.
“It was really a matter of timing that Iron Man became the first title for 4DX in Japan, though we were looking for a blockbuster action film, as that is what works best with the system,” Korona World spokesman Tagiki Ishiguro told The Hollywood Reporter. “The programming for the various effects is done in advance by CJ.”
"CJ" is the CJ Group, which is behind the technology for the 4DX format.
Several theaters around the world already screen films in 4DX, but the CJ Group is trying to bring 4DX to the U.S. this year.
