Disney is possibly looking at the biggest box office success in history, with Avengers: Endgame potentially achieving a $300 million opening weekend performance.

Tickets for the highly-anticipated film went on sale last week, along with a new, one-minute teaser.

Marvel fans crashed ticketing websites and broke the pre-sale first-day record, passing Star Wars: The Force Awakens.Avengers: Endgame sales have exceeded all expectations... to become Fandango’s top-selling title in its first 24 hours of sales, and it accomplished that feat in only six hours,” Fandango Managing Editor Erik Davis said in a statement. “We’ve never seen anything like this – it’s truly a groundbreaking accomplishment – as fans simply cannot wait to see how this epic saga comes to a close.”

The high demand for tickets has led to e-commerce sites like eBay providing tickets, too, but at insane prices. A pair of Endgame tickets were auctioned at $2,500, but one fan used the option to bypass other potential bidders and buy the tickets immediately. The highest bidder for the pair of tickets paid a whopping $15,000 to see the film at an AMC theater in West Orange, New Jersey.

A whole $15,000! The only way I'd pay that much for a movie ticket is if it comes with the opportunity of somehow appearing in the film myself.

There are also other listings for Endgame tickets that aren't ridiculously expensive, with prices ranging from $50 to $250 for one ticket--a major bargain relative to $15,000. And though we joke about the insanity of buying a ticket for that high of price, it goes to show how amped-up fans are to see arguably the most highly-anticipated film ever--superhero or otherwise.

Avengers: Endgame is out in theaters on April 26.
