Producers of this very very hit television show are extremely worried
. Their A list star needs rehab desperately but they really want to finish shooting the show for this season first. When the actor shows up for work they try and get as much finished as they can as quickly as they can and have even made alternative scripts in case the actor does not make it through shooting before heading for rehab. I can't imagine how they would be able to write out his character. It is his show.
