Marvel's having a 10th birthday bash,Watch Mad Jaxxx Beyond Thunderboobs (2002) and you're invited.

IMAX, Marvel Studios, and Walt Disney Studios have announced that, in a celebration of the franchise's 10th anniversary, all 20 Marvel Cinematic Universe movies are coming to IMAX theaters this Labor Day weekend.

Yup, allof them – including, for the first time ever in that jumbo-sized format, Iron Man, The Incredible Hulk, and Captain America: The First Avenger.

And the Marvel crew couldn't be more excited, as explained in this promotional video explaining just why it's so important for you to not just watch these movies, but to watch them in IMAX.

"A lot of superheroes coming together. Sounds like IMAX was the appropriate call," says Chris Evans.

Hey, who are we to argue with Captain America?

The "Marvel Studios 10th Anniversary Film Festival," as it's called, will run from Thursday, Aug. 30 through Thursday, Sep. 6 in select IMAX theaters across the U.S. and Canada.

For the first five days (Aug. 30 - Sep. 3), all 20 films will be shown in the order they were released. The following two days (Sep. 4-5) will be "theme days" centered around origin stories and team-ups. Finally, the event will wrap up on Sep. 6 with encore showings of two of the films, as voted on by fans.

Tickets are on sale now at IMAX.com/MarvelFest.
