Arnold Schwarzenegger has denied there's a parallel between film and real-world gun violence.
The 65-year-old former governor of California returns to movies as the sheriff of an Arizona border town in The Last Stand, his first leading role since serving as The Governator for six years.
"I personally feel that this is entertainment," he said. "The other thing is a serious real life tragedy.
"I think that we are going to continue doing entertainment. That is what we are doing as our profession, but at the same time, we all have a responsibility, I think, to improve the situation that we are in."
Arnie said it was important not to stigmatise mental illnesses and cited parenting, education, security and gun laws as contributing factors to the issue of gun violence.
"We as a society have the responsibility to look at this and leave no stone unturned," he said.
Despite returning to moviemaking with The Last Stand and last year's The Expendables 2, the former governor said he still wants to keep a toe in the political pool.
Arnie said his smaller part in Expendables 2 prepared him for his starring role in Last Stand, which also features Johnny Knoxville. He'll next be seen alongside Sylvester Stallone in The Tomb set for release later this year.
"I feel I have a bigger range, acting-wise," Arnie said. "It could be because of the age. It could be because of my experience that I have had now as governor."
