Hollywood is converting blockbuster films into 4-D because cinemagoers are shunning pricey multi-dimensional 3-D versions
But the experience has left some fans feeling sick, damp and pummeled after watching movies like Kung Fu Panda 2 and the latest Pirates of the Caribbean box-office hit.
A Korean company has built cinemas with seats which rock and special effects like wind, fog, strobe lights and scents are synchronised with the on-screen action.
The company, CJ 4DPlex, has opened an office in Los Angeles where computer programs are written for the action films.
It plans to build America's first 4-D screen multiplex in New York and if it is a success, they will expand into Europe.
