A total of 18 people complained about the posters for the film, which were released in the UK in June.
One ad featured Jolie lying on her back across the bonnet of a car, holding a gun next to the text: "We drove through the night at breathtaking speed, destroying everything in our path … welcome to the fraternity. We are a team of assassins, the weapons of fate. Kill one, save a thousand."
Another advert, headlined "6 Weeks ago I was just like you" and with the text "And then I met her ... and my world was changed forever," suggested McAvoy's character's life had been changed for the better since he had become an assassin.
"We acknowledged most viewers would understand the posters reflected the content of an action film," the ASA said in a statement. "However, we considered that because the ads featured a glamorous actress, action poses, several images of, or related to guns and aspirational text, they could be seen to glamorize the use of guns and violence."
While Universal Pictures UK defended their images, it also said the images had already been taken out of circulation, with no plans to use them again in the future.
