Nearly 8.5 million people went to the movies to celebrate National Cinema Day on Sunday, Aug. 27 as cinemas offered tickets for only $4 across all screens and formats. The number is a 5% increase from last year's inaugural event which saw approximately 8.1 million attendees, the National Cinema Foundation shared in a press release.

The second annual cinema day collected $34 million at the box office, a significant increase from last year’s returns of approximately $24 million. More than 3,000 locations and 30,000 screens across the U.S. and Canada participated in the one-day-event and theaters sold-out showtimes in all formats throughout the day, the National Cinema Foundation reported.

The box office witnessed a 16% increase over the previous Sunday, Aug. 20, said a statement by the National Cinema Foundation. Most moviegoers were aged between 18 and 34, according to ComScore, with women turning out in slightly higher numbers than men, making up 52% of the audience.

“National Cinema Day was a significant success in bringing together millions of film fans of all ages to enjoy movies on the big screen,” Bryan Braunlich, Executive Director of The Cinema Foundation shared in a statement.

“Movie theaters and all our partners helped maximize the impact of the day with creative marketing and special promotions that added to the overall excitement, while a diverse slate of exciting films provided something for everyone to see."

Besides discounted tickets, most cinemas also offered discounts on concessions and snacks, further attracting audiences.
