How Movie Theaters Are Gearing Up for 'Avengers: Endgame'

“Avengers: Endgame” could rake in a record-breaking $1 billion worldwide in less than a week, and movie theaters across the U.S. are preparing for an avalanche of customers. The blockbuster will be shown in more than 4,600 theaters in America and Canada when it opens, making it the widest release in movie history. Many theaters are planning 24-hour screenings to accommodate the demand to see the final installment of the "Avengers” series. Fandango says 4,000 shows are already sold out.
