The Girls creator and star voiced her support for the move after her show's producer Tami Sagher uploaded a photo of the movie poster, in which leading man Damon is featured holding a firearm, in a New York City subway station. The image of the gun had been peeled away, and Tami called for all billboards to receive the same treatment - a motion which won the support of her pal Lena.

The actress subsequently shared the post on her Instagram page earlier this month (Jul16), adding, "Good idea...Let's go!"

Their calls followed the deaths of African-Americans Alton Sterling and Philando Castile, who were shot by police officers in separate events, and the subsequent murders of five officers by a sniper at a Black Lives Matter protest in Dallas, Texas earlier this month (Jul16).

Matt and his co-star Julia Stiles have since responded to the social media movement, claiming they understand the sentiments behind Lena and Tami's messages, but they insist the movie does not promote violence. The actor also explains it wouldn't make sense to pull pictures of guns from the film's marketing materials because of the nature of the action thriller.

"For the marketing purposes of Jason Bourne - I mean he is a guy who runs around with a gun, so it's not gratuitous marketing, but certainly in light of recent events I understand that impulse to want to tear the gun out of the picture," he told E! News.

Stiles added, "Obviously there's an incredible amount of violence going on in the world and in the United States right now that's devastating, but this movie's perspective is not one that glorifies or makes heroic the idea of being violent. In fact, it's the opposite."

"The main character, Jason Bourne, is very much struggling with his own conscience, and the reason that he's been tortured throughout the whole series is because he regrets having to kill people for what he thought was a good cause," she continued. "I feel like it promotes the idea of questioning violence and questioning your government."
