Time to bust out the box office camping set.

Avengers: Endgame, the final installment of the current phase of the Marvel Cinematic Universe, is hitting theaters this month on April 26th, 2019. It’s gonna be a big deal, to say the absolute least, finally showing us the aftermath of Thanos’ infamous snap and a universe with half its population gone. A new short trailer released today teasing the long-awaited reconciliation between Iron Man and Captain America, who have been at odds since Captain America: Civil War.

Tickets for the film are now available on ticket-selling sites like Fandango, as well as sites for specific theaters like AMC. If you want to get your tickets now, though, you’d better be prepared to wait. According to reps from Fandango, so many people are trying to purchase tickets at the same time, it’s begun to adversely affect the site. Fandango is showing wait times of over an hour to purchase tickets, with similar states showing across other ticketing sites.

If you want advance tickets for opening night, well, let’s just hope you know a guy, ’cause online tickets may soon no longer be an option.
