There are few greater playwrights in the English language than Tom Stoppard -- Sir Tom Stoppard, that is to you.
This production is beautifully staged. The set is very modest and the actors really move around and use it in a way that helps to make the story compelling. There's a lot of music in this production, with the actors even singing along to a diverse number of songs like "Do Run Run" and "Whiter Shade of Pale." And, of course, the acting is great (well ... almost all of it). Cynthia Nixon, as always, is great. As wonderful as she was on Sex and the City, she really is one of the great stage actresses of her generation and is a joy to watch on stage. Josh Hamilton is very good as Max, making the most of the one of the most thankless parts I've ever seen in a play.
The biggest revelation is Maggie Gyllenhaal. Man, she is a GREAT actress. I've seen her in some movies like The Dark Knight and she was good. But on stage, with a great material like Stoppard, she really shines. Her Annie is such a complex, sexy creation that you can't take your eyes off her for a second. She generates so much power from the stage that you leave the theater thinking not just about what a great writer Stoppard is but what a great actress Gyllenhaal is. She inhabits Annie so completely that I'm still thinking about her performance. She's just a joy to watch.
The same, sadly, quite can't be said about Ewan McGregor. He is a very good actor and I loved him in Trainspotting (who didn't?). Also, he was the only decent thing in the Star Wars prequels. But he's a less than compelling Henry. In the play, Henry is supposed to be a great writer and a lousy human being. In fact, he's kind of a prick. That's part of what makes his evolution in the play into a good husband and father so important. But McGregor is just too likeable, too decent, too ... unprickish ... that this evolution doesn't really register with the audience. I will, however, admit a bias: in the revival I saw in 2000, Stephan Dillane (better known today as Stannis Baratheon in Game of Thrones) played Henry and he was incredible (won a Tony for it, in fact). McGregor just doesn't compare. I tried to seperate the two performances in my mind but just couldn't: while McGregor's Henry is passable, it just didn't work for me the same way Dillane's did.
However, these feelings aside, this Real Thing is a production worth seeing.
