Exactly. I've come to the conclusion that she must be very unlikeable or unprofessional (perhaps both) if all the work has dried up. There is usually a good reason why people don't employ you anymore.
I believe at the time she was meant to be earning something like £18000 a night. When you turn your nose up at that kind of money and that kind of opportunity given to you by one of the richest and most powerful men in stage and screen production, Sir Cameron Mackintosh. Then when you allegedly get off your face and act like a fangirl at The Golden Globes after party, it's not surprising if Richard Curtis doesn't put in a good word for you anymore or others decide they'd rather not bother hiring you.
