Gary Coleman (yes, that Gary Coleman) is the building superintendent from the Tony-award winning musical, Avenue Q. In the original Broadway show, Natalie Venetia Belcon played the role after the real Gary Coleman never showed up for a meeting to discuss his involvement with the role. Currently Carla Renata is playing the role. However, several male actors have also played the role, especially in the UK productions when black actresses aren't available. In the Australian productions, Gary is a white character.
When the real Gary Coleman passed away, the scriptwriters changed several of the character's lines instead of taking the character off of the show.
