It might have scored top of the North American box office , but "Justice League " didn't have the super opening weekend predicted, falling short of expectations with takings of $96 million, according to industry estimates released Sunday.

With an all-star cast including Gal Gadot as Wonder Woman, Ben Affleck as Batman and Henry Cavill as Superman, "Justice League " -- based on the DC Comics superheroes team -- sees a mash-up of classic characters fend off the threat of supervillain Steppenwolf (Ciaran Hinds).

The big-budget Warner Bros. production -- which fared better internationally, taking $185 million -- was forecast to earn $110 million in North American cinemas, according to Variety.

Writing on Twitter, industry analyst Exhibitor Relations -- which released the estimates -- said "Justice League " "may be the first film to debut w/ $96M that feels like a major disappointment."

In at second -- earning $27.1 million -- was Lionsgate's newly-released "Wonder," according to the box office tracker.

Starring Julia Roberts, Owen Wilson and Jacob Tremblay, "Wonder" follows the journey of August Pullman, a young boy with facial deformities, as he enters the fifth grade at a mainstream school for the first time.

After thundering to the top spot last week, "Thor: Ragnarok" slipped into third place in its third weekend in cinemas, taking $21.8 million.

Featuring the self-mocking humor of Chris Hemsworth as the powerful Norse god alongside Cate Blanchett as Hela, goddess of death, "Thor" has raked in an impressive $247.4 million since its release in North American cinemas.

Paramount's "Daddy's Home 2" halved its earnings from last weekend, dropping to fourth place with $14.8 million.

The festive comedy stars Will Ferrell and Mark Wahlberg as Brad and Dusty, who join forces to give their kids the perfect holiday -- an effort challenged when their own fathers show up.

In at fifth was Fox's "Murder on the Orient Express," earning $13.8 million.

The fourth television or cinema adaptation of Agatha Christie's classic detective novel, the murder mystery was directed by Kenneth Branagh, who also stars as part of an A-list cast including Johnny Depp, Penelope Cruz and Judi Dench.

Rounding out the top 10 were:

"The Star" ($10 million)

"A Bad Moms Christmas" ($6.9 million)

"Lady Bird" ($2.5 million)

"Three Billboards Outside Ebbing, Missouri" ($1.1 million)

"Jigsaw" ($1.1 million)
