After officially announcing ‘Guardians of the Galaxy’ at Comic-Con, Marvel has started more work into the “space adventure movie”. Nicole Perlman, a graduate of Marvel’s now defunct writer’s program who previously wrote two real-world space films about Neil Armstrong and the Space Shuttle Challenger, wrote the first draft of the first non-sequel of Phase Two, and now the studio has enlisted Chris McCoy to do a rewrite and add some “quirky comedic bents”.

According to The Hollywood Reporter (via Collider), McCoy is best known for showing up on The Black List on three separate occasions. This is the list of Hollywood’s hottest unproduced scripts of the year, and though it’s somewhat turned into a popularity contest around town complete with politics, it’s still an achievement to make the list once let alone three times.

In addition to the revelation of the new writer, the article also clarifies the team members that ill be appearing in the movie. Previously, when ‘Guardians of the Galaxy’ was still a rumor, the team was speculated to include Star-Lord, Drax the Destroyer, Gamora, Groot, Rocket Raccoon, and Nova. When the concept art was revealed in San Diego, all of those members made appearances with the exception of Nova. Here’s a more in-depth look at who these characters are and how they relate to some already established Marvel Cinematic Universe elements:

Drax The Destroyer, a human resurrected as a green warrior with the sole purpose of killing Thanos (the villain in ‘The Avengers’ final scene tease); Groot, a giant tree-man; Star-Lord, a gun-toting half-human/half-alien inter-galactic vigilante; Rocket Raccoon, a genetically engineered animal with a knack for guns and explosives; and Gamora, the last survivor of her species who was saved by Thanos to be his assassin but now battles him.

Based on reports we’ve been getting, ‘Guardians of the Galaxy’ will be the last of the Phase Two films (excluding ‘Avengers 2’, which doesn’t officially have a release date yet) to be shot since ‘Ant-Man’ may shoot after ‘Thor: The Dark World’, so who knows when we’ll get the next update on these intergalactic peacekeepers. All we know for sure is that the film hits theaters on August 1, 2014.
