‘Avengers’ tix demand clogs sites

It was an action-packed morning for “Avengers” fans.

Tickets for the long-awaited “Avengers: Endgame” went on sale Tuesday, though some reported issues securing their passes as waves of ticket-seekers flocked to movie sites like Fandango and AMC.

Some people lucky enough to have scored the tickets are looking to cash in, with prices reportedly up to $500 on eBay.

Marvel also released an intense new teaser that provides the first glimpse of the villainous Thanos in the movie.

“You could not live with your own failure,” Thanos, played by Josh Brolin, intones in the 60-second clip. “Where did that bring you? Back to me.”

The new “special look” teaser accompanied tickets being made available online, beginning with special showings on the night of April 25.

Many social media users said their AMC app went down once tickets for the highly anticipated flick went on sale, while others wrote of error messages. Fandango users also experienced issues, including long wait times.

“Can’t believe #Thanos already won the #Endgame by destroying half of the AMC’s server!” wrote one Twitter user.

“We want everyone to be able to grab their Avengers: Endgame tickets, but it looks like we’ve gotten Thanos’ snap,” the AMC Guest Services account tweeted Tuesday morning. “We’re working on getting things back up and running, and in the meantime, please keep trying our website and our partner sites!”

The movie premieres everywhere on April 26.

The movie serves as a followup to “Avengers: Infinity War,” which is the fourth-highest grossing movie of all time after taking home more than $2.04 billion at the global box office.
