Sean Hayes will be pulling a triple duty on NBC this fall. The Emmy winner, who executive produces the NBC drama Grimm, will do a multi-episode arc on another NBC sophomore drama, Smash. He will play Terrence Falls, a comedic television and film star who is making his Broadway debut in the musical Liaisons, based on the novel Les Liaisons Dangereuses. Due to a series of comic circumstances, he becomes a major thorn in the side for Ivy Lynn (Megan Hilty) and other characters. In addition to his stint on Smash, which reunites Hayes with Will & Grace co-star Debra Messing, he also is set to appear in a multi-episode arc on the upcoming second season of NBC’s comedy Up All Night as Ava’s (Maya Rudolph) former accompanist.
