Chuck Hemmingway (Stanley)
If you search Chuck Hemmingway (the guy who played Stanley) it says on the IMDB.com page that he died in the 1990"s. It doesn't give any specifics about his death.
I emailed Joe Rubbo via Facebook, he had no idea about Hemmingway's death. He is curious, just like me. I solely going on the info at IMDB.
