The ART's Holiday Family Show. From their website:
On the Arable family farm, a miracle is about to begin. In order to save young Wilbur from the butcher, Charlotte—a very special spider—hatches a plan to show the world how “radiant” one pig can be in the eyes of a true friend.
Adapted from E.B. White’s beloved children’s classic and directed by Dmitry Troyanovsky (James and the Giant Peach), Charlotte’s Web will feature graduate students from the A.R.T. Institute for Advanced Theater Training Class of 2018.
