Guardians of the Galaxy promises to be a very different Marvel film, featuring a cadre of fresh heroes and a surprising number of funny moments, if the trailer is any sign. With an August 1st release date, Guardians set to be Marvels big film of the summer, and it wants to start getting fans excited already: on July 7th, fans will be able to see 17 minutes of the film, in 3D, at 150 IMAX theaters across North America. Tickets are free, and all in attendance will receive what Marvels calling a limited-edition collectible poster for the film, which you can see below.
