The upcoming Friends reunion is set to feature all six of the Friends cast, a number of celebrity appearances such as David Beckham and Justin Bieber, and most importantly cameos from the obscure Friends characters. The actors who play Gunther, Janice and Richard are all expected to make an appearance for the celebratory episode. But what exactly have the actors who played these iconic roles been up to since the show aired? Friends is obviously about the main six but hardly an episode went by without a new character popping up. Throughout the years there were a number of recurring characters that became integral to the show. I’m talking Carol, Susan, Gunther and of course Mr Treeger.
