The reason Marin hasn't been doing much in NY lately is for a couple of reasons: (and this is from Ms. Mazzie herself)
1) She's moved to L.A. to pursue a film and TV career. This is less demanding/stressful work for her. The pressure of being an 'above the title' star is immense on Broadway. The producers are banking on your presence and 110% effort eight times per week.
2)There hasn't been much in NY that has interested her in the last few years. She would really like to do a straight play though.
It is a shame that she hasn't done more theatre lately. I see her as the epitome of a leading lady. Ragtime is the first show I obessesed over and the Marin/Brian/Audra trio of that show will always be immortal to me. I got to see Marin perform "Back to Before" with the Boston Pops the summer after the show opened and I was in absolute awe of her talent.
"If this is going to be a Christian nation that doesn't help the poor, either we have to pretend that Jesus was just as selfish as we are, or we've got to acknowledge that He commanded us to love the poor and serve the needy without condition and then admit that we just don't want to do it." -Stephen Colbert
