Cheryl Hines was on the Late Show a little while ago.
She was asked if it had finished and she gave no indication of it. She
said that they'd hopefully start filming the new season soon.
There was a lot of confusion around the title of that season.
But then again, maybe LD is just deciding, and wanted to make that
episode the best it could be, just in case he finishes it.
Which I must say.. is quite a pitty of it has finished. I don't feel
Curb got the recognition it really deserved.. Though, not exactly
unexpected, given LD's history of... quitting (not to sound harsh).
