Filmmaker Kevin Smith posted to his social media accounts today that he survived a “massive” heart attack last night after his stand-up performance at the Alex Theatre in Glendale, CA.

The 47-year-old filmmaker, best known for writing and directing Clerks and Chasing Amy, as well as starring in said films as the latter part of stoner duo Jay and Silent Bob, wrote that he went to the hospital after feeling ill after the first of two planned shows for the night. After cancelling his second performance to seek medical treatment, Smith said that the doctors discovered that he had had a “massive heart attack” with 100% blockage of the LAD artery, aka “the Widow-Maker.”

The last four movies that Kevin Smith has worked on as a director—Red State, Tusk, Holidays, and most recently Yoga Hosers—have all been horror movies or have had horror elements. Much different from the comedies and dramedies set in the “View Askewniverse” he’s best known for, such as Clerks, Mallrats, and Dogma. He’s also been involved in a couple of TV shows on The CW recently, directing a couple of episodes of both The Flash and Supergirl.

There’s been talk here and there of returning to his Askewniverse again for Clerks III, a world he hasn’t visited since 2006’s Clerks II. But now Smith has revealed that Clerks III is dead and he’s turned his attention to the most familiar part of the Askewniverse, Jay and Silent Bob, who he’s written a new movie for.
