GOTG2 clip and trailer description
The clip features Yondu, Rocket, and Baby Groot (who looks like a toddler version of the twig at the end of Guardians) imprisoned by the Ravagers. The Ravagers mistake Groot for a harmless twig that is “too cute” to kill. Yondu and Rocket then proceed to have Groot fetch them Yondu’s head fin (which controls his remote arrow) but Groot routinely fetches the wrong thing (including a severed finger and an office desk).
Once Groot succeeds in reuniting Yondu with his fin, Yondu uses the arrow to kill the ravagers (a LOT of Ravegers) and escape the ship.
Last up, Groot gets revenge (imagine a running and screaming six inch tall Groot in a jumpsuit) on a guard that wanted to poke his eye out earlier in the clip.
The trailer opens with the Guardians on top of an alien skyscraper – awaiting an inter-dimensional beast they have been hired to kill. Gamora is holding an alien rifle – which surprises Quill (who assumes swords are her go-to weapon). Zamora then chastises Quill for thinking she’d try to take-on an inter-dimensional alien with a sword. The scene ends with the alien creature appearing in the sky.
Throughout the trailer, Fleetwood Mac’s “The Chain” is played.
The rest of the trailer is a sizzle reel of fun shots (and hat tips to the original film). Each of the characters get a quick spotlight moment:
Star-Lord is shown gearing up for battle (his helmet re-materializing over his face) and blasting off.
Gamora is shown leaping at that inter-dimensial creature and stabbing it with… her sword (maybe the rifle wasn’t the best choice after all).
Rocket is shown once again spinning in circles firing guns – this time with Groot on his shoulder.
Drax is shown standing on an alien planet looking up and saying: “Screw Spaceships” (that’s a metaphor) and then, in a different shot, stabbing an organic looking wall repeatedly.
New Guardian, Mantis, is introduced to the team.
Ego (Kurt Russell’s character) is revealed as Star-Lord’s father. Explaining that, before Peter Quill was born, he took human form and met Quill’s mother. Drax questions if Ego’s human form includes a penis, to which Ego replies: “Yes, Drax. I do have a penis. A pretty good one too.”
