36 Behind-the-Scenes Secrets of Friends You Definitely Don’t Know
Matthew Perry struggled with addiction during his time on the series
This is definitely one of the darker behind-the-scenes secrets of Friends! Matthew Perry has always been open with his addiction struggles, but many don’t realize that he was struggling while starring in one of the greatest sitcoms of all time. In 1997, he completed a 28-day rehab program for an addiction to Vicodin. This was during the show’s third season, around the time you could noticeably see Perry getting super thin. There was even a nonsensical episode about Chandler and Monica working out that just didn’t play because it was clear Perry was too skinny! The actor got clean for a bit but re-entered rehab in 2001 during the show’s seventh season.
