With three weeks left to go before its big-screen debut, DC Comics and Warner Bros.' Justice League is tracking to open in the $110 million-$120 million range domestically, according to early surveys.

That would put it behind such DC titles as Batman v. Superman: Dawn of Justice ($166 million) and Suicide Squad ($133.7 million). Box-office observers note that Warners has yet to make its final marketing push. Also, rival superhero title Thor: Ragnarok, which debuts domestically on Nov. 3, could be obscuring tracking. Thor could debut as high as $125 million for Marvel Studios and Disney.

The all-star superhero tentpole — directed by Zack Snyder with additional input from filmmaker Joss Whedon — is a key moment for the DC Extended Universe, which hopes to emulate the success rival Marvel Studios has enjoyed with its Avengers franchise.
