Paramount Pictures said it was a "usual and longstanding practice in the film industry that cinema trailers and television advertisements" be produced to promote a film weeks or months before completion of the film's final editing.
"Thus, despite our best intentions, it is always possible that certain scenes appearing in an advertisement or trailer may not appear in the final version of a film," the company told the ASA.
Paramount Pictures said "the explosion in question was a single split-second element omitted from a 130-minute long action film and [we] believe that, taken as a whole, the impression created by the advertisement was a true and fair reflection of the film which could not reasonably be considered misleading or deceptive to customers".
As the advertisement had ceased airing and Paramount Pictures had offered the ticket refund, the ASA deemed the complaint "settled".
The Commercial Approvals Bureau, which approved the trailer to be aired on television, believed the advertisement posed "no threat of confusion to the large majority of TV viewers", and the complaint should not be upheld.
