The rule is everyone goes and no one talks about what happens inside the walls. It is a very well known AA meeting. The biggest of the big celebrities attend, but homeless people and those scratching on a daily basis to get by are there too. It is the great equalizer and everyone knows the rules. Apparently the permanent A list mostly movie actor got tired of those rules though and tried to ban everyone who wasn't famous and then tried to get people to stop attending and instead have the meeting at his place. The actor is not well liked for his actions.
