On the show, Falls is making his Broadway debut in the musical "Liaisons," based on the novel " Les Liaisons Dangereuses." Per NBC: "Due to a series of comic circumstances, he becomes a major thorn in the side for Ivy Lynn ( Megan Hilty) and other characters."
So will Messing and Hayes share any screen time? We'll have to wait and see.
Hayes will also make a guest appearance in a multi-episode arc on NBC's "Up All Night" as Ava's ( Maya Rudolph) former accompanist.
