National Theater, London (through June 15)

SEATS 111

The show’s European premiere is the third production of “The Flick” overseen by David Zinn, a Tony Award nominee this year for his set design of “The Humans.” The chairs in London are the same he used for the show’s 2013 premiere at Playwright Horizons — there were 105 seats there — and for its commercial transfer last year at the Barrow Street Theater, which featured 77 seats. They came from the Great Eastern Seating Company, a Pennsylvania company that sells new and used chairs.

“We added some gum to them in the front row, but all that wear is how they came, which is why we love it so much,” Mr. Zinn said. “It’s nice to know that there’s a warehouse somewhere filled with dirty movie theater seats.”

The on-set projector, flown overseas after being used at Barrow Street, proved to be a challenge, and not just because London theaters run on a different voltage than those in the United States.

“What’s complicated is that we are asking a film projector to behave unlike a film projector: Start immediately and shut off immediately,” he explained. “We had to Frankenstein projectors together to allow that to happen.”
