(CBS) -- Fans of the Avengers and the Disney Marvel franchise have been waiting for the moment to secure their spot to see the latest film in the series, "Avengers: Endgame".

But it seems AMC's website was not prepared for the masses who tried to buy tickets when the pre-sale period began Tuesday.

AMC’s website and its ticketing app appeared to be down because of the high demand. The theater chain addressed the issue on Twitter.

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

Fandango was operational, but was ticket purchasers still had long wait times.

"Endgame" is the sequel to "Infinity War", which made a record $640 million in its opening weekend and made more than $2 billion worldwide.
