Re-released in FEELARAMA

During the height of the disaster movie craze of the 1970's, KRAKATOA: EAST OF JAVE was re-released under the name of VOLCANO to cash in. SENSURROUND was the big gimmick at the time (winning an Academy Award) and gave viewers of EARTHQUAKE a jolting experience! Trying to catch a quicker buck with this moldy oldie, the producers not only changed the title but released it in FEELARAMA! A copy of the rare release poster art (showing the FEELARAMA gimmick and title change) is currently for sale on ebay (and way too rich for my blood: http://cgi.ebay.com/KRAKATOA-Feelarama-R74-Orig-1sheet-Movie-Poster-Rolled_W0QQitemZ230145049620QQihZ013QQcategoryZ2322QQrdZ1QQssPageNameZWD1VQQcmdZViewItem.

If this is viewed months after the auction closes, I've saved the photo here:

Apparently FEELARAMA used the same basic technology (and equipment?) as SENSURROUND...
