Even with Captain America: The Winter Soldier, The Amazing Spider-Man 2 and X-Men: Days of Future Past behind us, summer 2014’s roster of comic book movies is still looking pretty busy. Upcoming adaptations include Snowpiercer, Hercules, Sin City: A Dame to Kill For and Marvel Studios’ second offering for 2014 – Guardians of the Galaxy.

Previous trailers for Guardians of the Galaxy have played up the fun and comedic elements of the movie – probably a wise approach, since Marvel is trying to sell a movie with a talking alien raccoon and an anthropomorphic tree – but the new international trailer takes on a more serious and dramatic tone. In fact, there isn’t a single 80s song in earshot.

Peter Quill once again leads the charge in the trailer, which kicks off by showing his departure from Earth as a child. It also looks like we’re in for quite a bit of banter between Star-Lord and Rocket Raccoon (voiced by Bradley Cooper), the latter of whom apparently has quite a lot of “anger issues.” Let’s hope that none of those emerge while he’s busy building bombs.

The Guardians’ two specialists in the field of killing, Drax and Gamora, have unfortunately been somewhat sidelined in previous trailers as the marketing focused on the group’s charismatic leader, but Zoe Saldana does get a couple of lines in this trailer. Even Groot gets in an “I am Groot,” so Drax is the only Guardian so can’t get a word in edgeways. We may have to wait until the movie comes out to see the “emotional range” of the character promised by Dave Bautista.

Guardians of the Galaxy has a tough concept to sell to mainstream audiences and needs to strike a balance between humor and drama, but that’s something that Marvel movies so far have been able to do admirably. After the wave of praise that Captain America: The Winter Soldier received, let’s hope that Marvel can score two successes this year.

Guardians of the Galaxy is out in theaters on August 1st, 2014.
