Saw the matinee yesterday. I'll admit I was completely skeptical of Holliday's casting. Headley was simply inspired and Holliday, to me, just doesn't exude the regal beauty and sexuality that Headley does. Still, I went in with an open mind. While I was not completely won over by her performance, I'll concede that Holliday is absolutely working hard and if someone were seeing the show for the first time, I think they would be quite impressed with her performance. Unfortunately, at this early stage in her run, I would say she is passable, but she has a ways to go. I do expect, though, that in a few weeks she will have found her footing more and will be a little more engaged with and connected to the rest of the cast.
As it is, I found she and Cynthia lacked any chemistry, to me, it really seemed as though they were performing in two completely different shows, they never seemed to truly connect with on another. Vocally, Holliday shows incredibly restraint and only slips in a couple of those little tics that have sort of become "Holliday-isms." By and large, she does sound quite good. The book scenes, though, were a little shakier, it just didn't seem completely natural and she appeared to be trying a bit too hard at some points. I look forward to seeing her further in her run to see how her performance has progressed.
Costume-wise, all of her costumes are similar to those of previous Shugs, but there have been a few alterations. Her slip is significantly longer than the others have been, and she wears a bolero jacket over it. She no longer changes into her "Push Da Button" dress onstage. Instead, the staging has been altered, with her and Cynthia walking behind one of the upstage panels and changing up there. As Whizzer mentioned, her dress also has sleeves.
The blue skirt costume is largely the same, though the sleeves on the blouse are longer and there is a sort of peplum that comes over the top of the skirt. He Celie's Pants costume is, again, almost identical, but with a similar peplum over the top of the pants.
Staging-wise, Shug has been removed from appearing in "Miss Celie's Pants," and has been replaced by the Olivia track (Carla Stewart). The staging for "Push Da Button" is slightly different, with Shug no longer walking on the chairs, instead the church ladies do this while Shug sings in front of them. Holliday also does not join the rest of the cast in sitting on the ground for the final scene. While a bit awkward at first, her aforementioned health concerns explain these small alterations.
Overall, it was a very different experience and while I can't say I was overly impressed with Holliday's performance, I do think she has the makings of something, it just needs a little more fine tuning.
