Once the doors open and the audience settles in, actors will start appearing onstage and around various parts of the theater. I was in the mezzanine and was treated to a man, joined later by a woman, in suggestive play. I don't believe the main characters, such as Mr. Tveit, make pre-show appearances. But do not worry. In the can can seats you will get more than ample opportunity to see him up close and personal throughout the show. Have fun!
