Kevin Smith had a "massive heart attack" this weekend. The director/actor was in Glendale, LA at the Alex Theatre this weekend taping a new special with Comedy Dynamics. In between the first and second performances Smith was not felling well, cancelled the second show, and went to the hospital. It was that decision which appears to have ultimately saved Smith's life as doctors informed him that said heart attack is very much the kind that would take someone's life.
As he was recovering, Smith posted an image stating that he was still "above ground" and recovering.
As you can tell from photos earlier in the day, Smith was ready to go and film the specials.
