If pre-ordered tickets are any indication, Avengers: Infinity War is going to drop a bomb on box offices once it premieres April 27. All this on the heels of Black Panther, which broke $1 billion in global revenue last weekend and set a record for February premieres.

Fandango sent up the alarm on Friday when tickets went on pre-sale following the big reveal of the newest trailer yesterday. But Fandango did not share whole numbers (or revenue) of ticket sales, only that Infinity War had outsold flicks like Black Panther, and Batman v Superman: Dawn of Justice in pre-sold tickets, which apparently are a thing now.
