"How about people stop f--king shooting people?" tweets Armie Hammer.

The hashtag "#GunControlNow" started trending on Twitter Thursday morning after news of the latest massacre spread.
It marks a resurgence in America's cyclical gun control debate, which has gone quiet in recent months, but last captivated the national dialogue after the shooting at Marjory Stoneman Douglas High School, in Parkland, Florida, last February. Surprisingly, the divisive subject did not become a hot topic after the synagogue mass shooting in Pittsburgh, Pennsylvania, in late October.
"Legends of Tomorrow" star Brandon Routh, who also famously played Clark Kent in "Superman Returns," invoked the cry for elected official to take legislative action in his response to the shooting.
"My heart goes out to my fellow Californians. I'm gutted & heartbroken hearing about the deadly shooting in Thousand Oaks. This is part of greater Los Angeles -- hits close to home," he wrote. "Demand action from our newly elected officials. Help protect fellow Americans."

Ventura County Sheriff's Sergeant Ron Helus was one of the first responders and was met by gunfire. He died at the hospital, leaving behind a wife and son.

View Story"I have been fully briefed on the terrible shooting in California. Law Enforcement and First Responders, together with the FBI, are on scene. 13 people, at this time, have been reported dead," Donald Trump tweeted on Thursday morning. "Likewise, the shooter is dead, along with the first police officer to enter the bar....Great bravery shown by police. California Highway Patrol was on scene within 3 minutes, with first officer to enter shot numerous times. That Sheriff's Sergeant died in the hospital. God bless all of the victims and families of the victims. Thank you to Law Enforcement."
As Hollywood wakes up to the horrific news, many stars have also turned to social media to react -- offering up condolences, while also urging for action. Others praised Helus for his heroism. Also tweeting in the wake of the shooting was Cameron Kasky, one of the survivors of the mass shooting at Marjory Stoneman Douglas High School in February of this year.
"Westworld" star Clifton Collins Jr. even tweeted that he actually turned down an invitation to go to the bar last night, something he's now very grateful he did.
