The old 70s gimmick Sensurround returns in a new guise.

This will give a new generation the shakes and rumbles that Universal's Sensurround speaker system treated moviegoers to from roughly 1974 (with the release of EARTHQUAKE) to 1979 (the release of the original BATTLESTAR GALACTICA series pilot as a feature film).

And, as coincidence would have it, the D-Box Motion System will be first used on a Universal release--the upcoming fourth installment of THE FAST AND THE FURIOUS franchise.
