He has appeared as a character in shows like The Gifted and Hulu’s Marvel’s Runaways, but Stan has never appeared in person in any of Netflix’s Marvel shows.
The one exception is the brand new season of Jessica Jones where Lee is seen on a bus ad for law firm Forbush and Associates.
Interestingly, Lee is apparently playing the same character in every poster, NYPD Captain Irving Forbush.
He’s also appeared in all of Marvel’s current television series, though in many cases the appearance is even less “live” than Big Hero 6.
