Zachary Levi is back on Broadway in She Loves Me, and he’s living proof that musical theater is more energizing than caffeine. (That’s just science!) The stage and screen favorite stopped by Late Night to chat with Seth Meyers between his Wednesday matinee and evening performances—a time many performances might reserve for a nap or Schmackary’s break. But not Levi. “I get to the end of the show,” he explains, “and I’m so jazzed.” You can now catch the ever-so energetic Levi as Georg Nowack, opposite Laura Benanti, Jane Krakowski and Gavin Creel, in She Loves Me at Studio 54, where the revival opens officially on March 17.
