Paramount Pictures film studio apologised on Wednesday for a poster for its upcoming film "Teenage Mutant Ninja Turtles", showing the four characters jumping down from an exploding skyscraper underscored with a Sept. 11 release date.
Both posts received a barrage of criticism and were deleted, though some screenshots were still being shared on social media.
"We are deeply sorry to have used that artwork for the marketing materials promoting the September 11 opening in Australia," Paramount Pictures Australia said in an emailed statement to Reuters.
"Combining that image and date was a mistake. We intended no offence and have taken immediate action to discontinue its use."
In Australia it will be released on Sept. 11, the thirteenth anniversary of the al Qaeda militant attacks on U.S. cities and the destruction of the World Trade Center twin towers in New York.
