To promote its “Guardians of the Galaxy” — and help educate moviegoers on who its band of otherworldly misfits are — Marvel Studios will screen 17 minutes of “Guardians of the Galaxy” in select Imax theaters on July 7.

The first look will take place in 150 Imax locations across North America at 7 p.m. The film, directed by James Gunn, opens Aug. 1.

“We’ve re-mastered some of our epic sequences into the Imax 3D format, taking the scope and scale to new heights while creating a truly immersive, cinematic experience that will take you further into the Marvel Universe than ever before,” Gunn said.

Imax is offering the free tickets to the screenings now through “Guardians'” Facebook page.

Those who attend will also receive a limited-edition “Guardians” poster from Imax (see below).

“Imax and Marvel fans are some of the most die-hard in the world and we’re excited to offer them this exclusive extended first-look at one of the summer’s hottest upcoming movies in IMAX 3D,” said Greg Foster, senior executive VP, Imax Corp. and CEO of Imax Entertainment. “James Gunn’s visionary film in Imax 3D is going to give our audiences an immersive experience they won’t find anywhere else, and we’re thrilled to get the ball rolling and reward fans early at this unique event.”

“Guardians” stars Chris Pratt, Zoe Saldana, Dave Bautista, Lee Pace, Michael Rooker, Karen Gillan, Djimon Hounsou, with John C. Reilly, Glenn Close and Benicio Del Toro, and features Vin Diesel as Groot and Bradley Cooper as Rocket raccoon.
