Introducing the Frankenstein Monster Mash! Every Wednesday of the run of Frankenstein, Central Square Theater invites you and your friends to dress up for our weekly costume contest. Show up in your spookiest fit and receive one free item from our concessions booth—zombies, mad scientists, and all other manner of monsters welcome (or come as a character in Mary Shelley’s Frankenstein)! In addition, a winner will be chosen each night to be featured on our website, AND will receive free tickets to one of our shows later in the season! A grand prize winner will be chosen at the end of the run.
