Stan Lee, the man behind much of Marvel, has been hospitalized following undetermined heart problems. Deadline reached out to representatives of Lee, who said he’ll remain at Cedars Sinai hospital for a few days but offered no timetable for when he will be released or details regarding what happened.

Lee turned 95 at the end of 2017, and while age is just a number, there’s never any telling what number of things could be going on at the moment so we won’t speculate. We only wish Stan the best through this time and hope for a swift recovery!
