Kevin Smith, director of critically acclaimed comedies including "Clerks," "Chasing Amy," and "Zack and Miri Make a Porno," said he had a massive heart attack Sunday night.

Smith, 47, who is currently starring on the AMC reality series "Comic Book Men," was filming an episode of the show before the heart attack. He tweeted the news late Sunday along with a selfie from his hospital bed.

"After the first show this evening, I had a massive heart attack," Smith wrote. "The Doctor who saved my life told me I had 100% blockage of my LAD artery (aka "the Widow-Maker"). If I hadn't canceled show 2 to go to the hospital, I would've died tonight. But for now, I'm still above ground."
