LOS ANGELES — Dwayne “The Rock” Johnson outmuscled the competition at domestic movie theaters as the earthquake epic “San Andreas” hauled in an estimated $53.2 million over the weekend. It was Johnson’s biggest debut for a nonsequel as the top-billed actor, according to box office tracker Rentrak.

The action star helped the movie overperform on the West Coast despite fears that audiences in earthquake-prone regions would stay away, said Dan Fellman, president of domestic distribution for Warner Bros., which distributed the film made by its New Line unit.

“Some people felt they’d be a little nervous watching such a disaster hit both Los Angeles and San Francisco, but there was a curiosity factor,” Fellman said. “They went, they packed the theaters and they liked it.”

For the year to date, box office revenues for theaters in the U.S. and Canada are up nearly 5 percent at $4.26 billion, while attendance is up more than 4 percent.

Estimated ticket sales for Friday through Sunday in U.S. and Canadian theaters:

1. “San Andreas,” $53.2 million

2. “Pitch Perfect 2,” $14.8 million

3. “Tomorrowland,” $13.8 million

4. “Mad Max: Fury Road,” $13.6 million

5. “Avengers: Age of Ultron,” $10.9

6. “Aloha,” $10 million

7. “Poltergeist,” $7.8 million

8. “Far From the Madding Crowd,” $1.4 million
