Gatz, the signature creation of downtown theater troupe Elevator Repair Service (ERS), included every sentence of F. Scott Fitzgerald’s 1924 novel The Great Gatsby, with each performance running a whopping eight hours (including intermissions and dinner break). At the Public Theater these days (16 years after Gatz premiered there), ERS is offering its take on Ulysses, the ravishingly innovative novel—serialized in 1918, published in book form in 1922—that secured James Joyce’s position as preeminent pioneer of stream-of-consciousness narrative in English. As with Gatz, the script of Ulysses consists entirely of the novelist’s original prose; this time, though, there are numerous elisions, permitting each performance to clock in at a mere two hours and 40 minutes.
