Can anyone tell me what a 5D movie is?

Don't know. 4D supposedly added the element of smell. In the days of sfx, artist Ray Harryhousen it was popular to add vibrators to some or all of the seat.

Strictly speaking, a 4th dimension is time, and maybe a 5th dimension would be substance.

5D cinema they are all dimensional movie. When we are watching 3D movie we only can see solid pictures BUT now our engineer will bring you into a whole new world and make you immersive into the story. Seats move to 6 dof (degree of freedom ) controlled by computer so that when we watch 5D movies with 3D glasses we will catch the feeling of storm, lightning, rain, spray mist, lapping legs, bubble, snow which will be totally different from the old 3D movies. Fresh and exciting because of the good interactivity created by the new device we developed.
