“I think as filmmakers we should sit down — the Marty Scorseses, the Quentin Tarantinos and hopefully all of us who deal in violence in movies — and discuss our role in that,” Weinstein said.

But Weinstein — an avid supporter of President Obama — suggested the No. 1 culprit is the lack of gun control and said it is time for politicians to “put up or shut up” on the issue.

“If we don’t get gun-control laws in this country, we are full of beans. To have the National Rifle Association rule the United States is pathetic. And I agree with Mayor Michael Bloomberg: It’s time to put up or shut up about gun control for both parties. Mitt Romney better outline where he stands, and people know that I’m a firm supporter of the president and I believe he’s got to do the same,” Weinstein said…

“It’s a question that I wrestle with all the time. I’ve been involved with violent movies, and then I’ve said at a certain point, ‘I can’t take it anymore. Please cut it.’ You know, you’ve got to respect the filmmaker, and it’s a really tough issue. My heart goes out to those kids and those families,” Weinstein said later in the interview.
