The blockbuster box-office performance of "Avengers: Infinity War" has reinforced the power of movie-going, comScore senior media analyst Paul Dergarabedian told CNBC on Monday.
The Disney film shattered box-office records over the weekend, edging past "Star Wars: The Force Awakens" to set the highest opening weekend of all time. It brought in an estimated $258 million in domestic receipts.
"This is why people go to the movies. They're going to keep going this summer. This is going to be a really strong summer," Dergarabedian said on "Power Lunch."
"Infinity War" unites the Avengers and the "Guardians of the Galaxy" on screen for the first time, and further weaves in new characters, like "Doctor Strange" and "Spider-Man" into the Marvel Universe. It also features supervillain Thanos, who has lurked in the shadows of brief post-credit scenes and cameos for the last six years.
Dergarabedian said the run-up to "Infinity War" was "incredible, with movies like "Guardians of the Galaxy Vol. 2," "Spider-Man Homecoming," "Thor: Ragnarok" and the record-breaking "Black Panther" all doing well at the box office and with critics.
And the movie itself has a lot of staying power, he said. The next big release is not expected for a few weeks when "Deadpool 2" opens, followed by "Solo: A Star Wars Story."
"We could be looking a record-breaking month of May at the box office," Dergarabedian said.
It all goes to show that movie-going isn't dead.
"It's really based on the product. If the movies are good, people love going to the movie theater," he said.
