Paramount Australia executives have apologized after publishing a poster from upcoming film "Teenage Mutant Ninja Turtles" that features a burning skyscraper with the release date Sept. 11.
The artwork showed the titular heroes leaping from a burning building with the release date splattered across it.
Backlash prompted movie bosses to remove the image from Twitter. They said in a statement: "We are deeply sorry to have used that artwork for the marketing materials promoting the September 11 opening in Australia. Combining that image and date was a mistake. We intended no offense and have taken immediate action to discontinue its use."
Nearly 3,000 people died on Sept. 11, 2001, after terrorist group al-Qaeda flew planes into the World Trade Center in New York City as well as the Pentagon in Washington, D.C.
Once the poster was released, there was an outcry on social media, slamming the movie studio for its insensitive marketing.
Paramount has removed the offensive poster from its Facebook page.
The film centers on Shredder (William Fichtner) and his evil Foot Clan, who control the police and politicians. Then a group of four unlikely outcast brothers rise from the sewers and become Teenage Mutant Ninja Turtles. The Turtles must work with fearless reporter April (Megan Fox) and her wise-cracking cameraman Vern Fenwick (Will Arnett) to save the city and stop Shredder.
"Teenage Mutant Ninja Turtles" opens in U.S. theaters on Aug. 8.
