This morning, he tweeted from a hospital bed that he had suffered a "massive heart attack" between back-to-back standup shows.
"The Doctor who saved my life told me I had 100% blockage of my LAD artery (aka “the Widow-Maker”)," Smith tweeted.
"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!"
Smith was filming a new standup special, Kevin Smith Live!, at the Alex Theatre in Glendale Sunday night. The first show began at 6 p.m., and the second was scheduled for 9 p.m.
We are grateful to still have him.
