Yes it is, I remembered because it's also my Mom's birthday. Her movie also opened today and she got a nice notice from the New York Times and L.A. Times:

That bosom soon comes heaving into the picture, attached to the ripe, evocatively quivering figure of John’s mother, Julia (a very good Anne-Marie Duff). http://www.nytimes.com/20...es/08nowhere.html?src=me

Where Mimi is a keep-the-windows-locked kind of influence in his life, Julia is a throw-them-open-and-let-the-sun-shine-in sort. She's also a fragile flower, beautifully and seductively played by Duff.
