Jennifer Ehle was the true star though. I admit that the main reason I went was because she is an actress that I admire very much and when I heard that she was doing "the Philadelphia Story" I knew I had to go. But she seriously was fabulous. The audience loved her completely despite her selfishness and she conveyed the way that her character had to get over her inability to be anything less than severe on other people very well indeed. Her voice and diction was good and the accent that she delivered certain lines in was superb. There was one bit in particular that was my favourite. It was the way that her eyes widened wonderfully when she realised what her drunkeness the night before had led to with Connor. The whole audience, even the ones up with the gods laughed. It was really brilliant. She was really brilliant and the entire cast was very brilliant.
There is also another blogger review at Rullsenberg Rules:
Some have criticised the chemistry between Jennifer Ehle and Kevin Spacey as rather unconvincing. I think that a little harsh: the problem lies more with the dimensions of the inimitable KH for whom this was really structured and into whose shoes it would be hard to imagine any woman fitting. As such, Ehle works hard (but without it seeming to be an effort) to convey the mix of confident coolness and the coy irrepressible delight/frustration felt at CK Dexter Haven. That she does it as well as she does is a credit to her talents.
