man. dont post spoilers in a thread, where people are clearly saying, "I have not read this material, what should I read?"
my bad i didn't know ppl wanted to know more?
i will skip guardians of the galaxy pre 2005, because they were shit, there were the west coast avengers or the mississippi avengers, just crap.
but i have to preface this with the whole "marvel event"
there were 2 super major stories going on mid 2000.
1. was the story at home
2. the story in space
1. you might have heard was about the civil-war, forced registration of super-heroes, then iron man (and govt) vs. capt america (and friends), in the end all it amounted to was some black guy died... no seriously (goliath).
this event is tiny, when compared to the galactic and i do mean galactic event that is happening in space.
richard rider, formerly of "the new warriors" and just a guy that flies and shoots beams, is back at his galactic police forces homeworld xandar, they are basically the green lantern corps. While richard rider (we'll call him nova) is not the lowliest guy, he does ok, and is just a mid 20's kid by now that does the usual stupid things and choices a 20ish year old makes (this is his character so far). remember xandar and the nova corps are like the "green lantern corps" they are the galaxys police force and like the green power battery that gives a tiny bit of power to every green lantern, the xandar worldmind, gives a little bit of power to every nova corps.
Then, the "annihilation wave", simply put nova is on a floating rock, that used to be xandar, the galactic police force is destroyed in 1 swoop, and now we see Nova's story.
why am i so focused on Nova? because through nova we see the formation of the GotG, we see the relationships Nova built up transferred to the GotG, Nova not only re-booted himself from Grade B whiny teenager to Better than Iron Man, by proxy he rebooted GotG from a sliced together team with no character to this iteration that has a history of teamwork and survival.
in that regard i'll post some amazon links

http://www.amazon.com/Annihilation-B...ref=pd_sim_b_1
i'm pretty sure this 3 book series contains
Drax The Destroyer: Earthfall
Annihilation: Nova
Annihilation: Silver Surfer
Annihilation: Super Skrull
Annihilation: Ronan
Thanos
Annihilation
Annihilation: Heralds of Galactus
(my nephew has borrowed my collection for years... it might as well just be his, i have no reference)
this is all prequel stuff up until this point, NOW we have GoTG volume 2 (again volume 1 was the dorky 70's to 90's version)
http://www.amazon.com/Guardians-Gala...y+%28vol.+2%29
that could be it for you, if you want you could still read more GotG, but... you'd have to know the "war of kings" storyline which i'll explain but is also HIGHLY! involved and involves the "3rd ###mers brother"

i don't know anyone that even likes GotG pre 2005, this movie is most def gonna be based and we see it, on the 2005 post annihilation team.
