Zach Braff says he had a blast making his debut on the Great White Way in Bullets Over Broadway, but as the show comes to an end this weekend, he admits that all that dancing and singing night after night has worn him out.
“I am exhausted!” Braff, 39, told PEOPLE at an “appreciation party” that his co-star, Vincent Pastore threw for cast members at The New York Beer Company in Manhattan after their Thursday show. “But I had more fun doing this than in any other time in my life.”
Of course, Braff is tired, added Pastore, who played Big Pussy on the HBO drama, The Sopranos. “He did the show while finishing his movie! The guy is a trouper!”
Pastore said he is “sad” that the show, the musical adaptation of Woody Allen and Douglas McGrath’s 1994 film, which opened on April 10, is closing on Sunday.
“I’ve been doing the show since Jan. 15 and it’s been great,” he said. “I never missed a rehearsal or a show. My understudy hates me!”
Pastore, 68, says he learned that he had prostate cancer after he began rehearsals. “I had surgery and 40 sessions of radiation in between rehearsals,” he said. “It was pretty dramatic, but I had goals and my first goal was to make it to opening night. My next goal was to make it to the Tony Awards and my goal after that was to make it to the end of the run. I dance and I sing every night and am lucky to be here.”
On opening night, Pastore recalls running into Allen, who wrote the book for the show, rewriting jokes even during previews. “I said, ‘Woody, I had cancer.’ And he said, ‘Well, if you’re going to get cancer, get prostate cancer!’ I said, ‘Thanks, Woody!’ ”
