Superhero sequel "X-Men: Apocalypse" debuted as the top movie at North American box-offices this Memorial day weekend with ticket sales of $65 million, industry figures showed on Sunday.
In the United States, the three-day holiday weekend -- the unofficial start of summer -- is popular with moviegoers, and cinemas generally do a booming business, although box office watchers remarked that ticket sales this year have been uncharacteristically light.
Disney's "Alice Through the Looking Glass" opened in the number two spot, selling $28.1 million in tickets.
"The Angry Birds Movie" was third with $18.7 million.
Another comic book-themed flick, "Captain America: Civil War," was fourth with $15.1 million, according to industry tracker Exhibitor Relations.
"Neighbors 2: Sorority Rising," grossed $9.1 million for fifth place.
