Thanks to an anonymous post, earlier today I was alerted to an article in "Out" where Meryl is apparently quoted in a press junket saying that she will not be pursuing Master Class, the HBO production of Terrence McNally's play about opera diva Maria Callas. Mike Nichols was set to direct the film prior to his death in November 2014. Production was to begin in early 2015.
What's interesting, however, is that I decided to search for any other news on this possible quote, and the only other recent blurb I found was this from the Boston Herald, where again Master Class is mentioned. A direct question was posed to Meryl asking "where does that stand?" Her quoted answer here is a bit less definitive. She explains that after Nichols' death and the depth to which the two of them had gone into preparations for the production, she essentially lost interest in doing it without him. But it seemed a bit ambiguous in regard to the possibility that she would be open to doing it if someone else were at the helm.
My take away from this information is that Master Class is not going to be made with Meryl Streep starring. I don't think it's 100% dead, and being that it's such a compelling story and has gone through so many struggles to come to the screen, I hope it does eventually get made, even if it doesn't star Meryl. However, I'm surrendering hope that Streep has any immediate involvement in the film. Unfortunate.
