The on-sale announcement was paired with the last teaser for the Marvel film, which is about one minute long and shows much more footage of what to expect from the next chapter in the Disney blockbuster franchise.

The final spot for the highly anticipated Avengers: Endgame dropped Tuesday just as advance tickets went on sale — and the result was numerous sites, including AMC, being clogged with traffic. The last teaser for the Marvel film is about one minute long and shows a lot more footage of what to expect from the next chapter in the Disney blockbuster franchise. It seems Pepper Potts (Gwyneth Paltrow) lived, Tony Stark (Robert Downey Jr.) and Captain America (Chris Evans) make up and another huge battle with Thanos (Josh Brolin) will take place — not too surprising, but this is the first good look at Thanos in an Endgame trailer.

Not long after advance tickets went on sale, #AvengersEndgametickets was the No. 1 trend on Twitter, as fans were having trouble with clogged theater websites. When Heat Vision attempted to purchase tickets for opening day (April 26), the AMC site gave a 503 error code. Around 8 a.m., the website was down entirely. By 1 p.m., the site was running again. Around that time, Fandango announced that Endgame "crushed" the first day U.S. sales record set by 2015's Star Wars: The Force Awakens within the first six hours of presales. Fans on Twitter shared their own issues with other sites, including wait times of more than 30 minutes in a queue. On Wednesday, AMC confirmed that the "unprecedented" number of fans trying to get Endgame tickets indeed crashed the company's site and mobile app with traffic volume approximately 10 times higher than normal, and double AMC’s previous record, a spokesman told The Hollywood Reporter. As with Fandango, Endgame was AMC’s new U.S. first-day presale record holder, beating Force Awakens by approximately 50%.
