Gunn was hired to write and direct the film that September. In February 2013, Pratt was hired to play Peter Quill / Star-Lord, and the supporting cast members were subsequently confirmed. Principal photography began in July 2013 at Shepperton Studios in England, with filming continuing in London before wrapping in October 2013. In addition to an original score by Tyler Bates, the soundtrack includes several popular songs from the 1960s and 1970s chosen by Gunn. Post-production was completed on July 7, 2014.

Guardians of the Galaxy premiered at the Dolby Theatre in Hollywood, Los Angeles, on July 21, 2014, and was theatrically released in the United States on August 1 as part of Phase Two of the MCU. It was a critical and commercial success, grossing $773.3 million worldwide and became the third-highest-grossing film of 2014. It was praised for its screenplay, direction, acting, humor, soundtrack, visual effects and action sequences. It was nominated for two awards at the 87th Academy Awards, and received numerous other accolades. Two sequels have been released: Guardians of the Galaxy Vol. 2 (2017) and Guardians of the Galaxy Vol. 3 (2023).

Plot

In 1988, following his mother's death, the child Peter Quill is abducted from Earth by the Ravagers, a group of alien thieves and smugglers led by Yondu Udonta. In 2014, on the abandoned planet Morag, Quill steals a mysterious Orb but is attacked by henchmen of the fanatical Kree renegade Ronan the Accuser, led by Korath. Although Quill escapes with the Orb, Yondu discovers his theft and issues a bounty for his capture, while Ronan sends the assassin Gamora after the Orb.

When Quill attempts to sell the Orb on Xandar, the capital of the Nova Empire, Gamora ambushes him and steals it. A fight ensues, drawing in a pair of bounty hunters: Rocket, a genetically and cybernetically modified raccoon, and his companion, the tree-like humanoid Groot. Nova Corps officers capture the four, detaining them in the Kyln prison. An inmate, Drax the Destroyer, attempts to kill Gamora due to her association with Ronan, who killed his wife and daughter. Quill convinces Drax that Gamora can bring Ronan to him, though Gamora reveals that she has betrayed Ronan, unwilling to let him use the Orb's power. Learning that Gamora intends to sell the Orb to the Collector Taneleer Tivan, Quill, Rocket, Groot, and Drax work with her to escape the Kyln in Quill's ship, the Milano.

Ronan meets with Gamora's adoptive father, Thanos, to discuss her betrayal. Quill's group flees to Knowhere, a city planet inhabited by thieves and merchants made from the severed head of a dead Celestial. A drunken Drax summons Ronan while the rest of the group meets Tivan. Tivan opens the Orb, revealing an Infinity Stone, an item of immeasurable power that destroys all but the most powerful beings who wield it. Tivan's slave, Carina, grabs the Stone, triggering an explosion that engulfs Tivan's collection. Ronan arrives and easily defeats Drax, while the others flee by ship, pursued by Ronan's followers, including Gamora's adoptive sister Nebula. Nebula destroys Gamora's ship, leaving her floating in space, and Ronan's fighters capture the Orb.

Quill contacts Yondu before following Gamora into space, giving her his helmet to survive; Yondu arrives and retrieves the pair. Rocket, Drax, and Groot threaten to attack Yondu's ship to rescue them, but Quill negotiates a truce, promising the Orb to Yondu. Quill's group agrees that facing Ronan means certain death but that they cannot let him use the Infinity Stone to destroy the galaxy. On Ronan's flagship, the Dark Aster, Ronan embeds the Stone in his warhammer, taking its power for himself. He contacts Thanos, threatening to kill him after first destroying Xandar. Hateful of her adoptive father, Nebula allies with Ronan.

The Ravagers and Quill's group join the Nova Corps to confront the Dark Aster at Xandar, with Quill's group breaching the warship with the Milano. Ronan uses his empowered warhammer to destroy the Nova Corps fleet. Drax kills Korath, and Gamora defeats Nebula, who escapes. However, the group finds themselves outmatched by Ronan's power. Rocket crashes a Ravager ship through the Dark Aster. The damaged Dark Aster crash-lands on Xandar, with Groot sacrificing himself to shield the group. Ronan emerges from the wreck and prepares to destroy Xandar, but Quill distracts him, allowing Drax and Rocket to destroy Ronan's warhammer. Quill grabs the freed Stone, and with Gamora, Drax, and Rocket sharing its burden, uses it to vaporize Ronan.

Quill gives Yondu a container supposedly containing the Stone and gives the real one to the Nova Corps. As the Ravagers leave Xandar, Kraglin Obfonteri remarks that it turned out well that they did not deliver Quill to his father per their contract. Quill's group, now known as the Guardians of the Galaxy, has their criminal records expunged, and Quill learns that he is only half-human, his father being part of an ancient, unknown species. Quill finally opens the last present he received from his mother, a cassette tape filled with her favorite songs. The Guardians leave in the rebuilt Milano along with a potted sapling cut from Groot, which grows into a baby version of him.

In a post-credits scene, Tivan sits in his destroyed archive with two of his living exhibits: a canine cosmonaut and an anthropomorphic duck.

Cast

Chris Pratt as Peter Quill / Star-Lord:The half-human, half-alien leader of the Guardians who was abducted from Missouri as a child in 1988 and raised by a group of alien thieves and smugglers called the Ravagers. About the character, Pratt said, "He had a hard time as a kid, and now he goes around space, making out with hot alien girls and just being a rogue and a bit of a jerk, and through teaming up with these guys, finds a higher purpose for himself". He also added that the character is a mix of Han Solo and Marty McFly. Pratt, who was mostly known for playing supporting characters, including Andy Dwyer on the television series Parks and Recreation, initially turned down the role. Pratt had lost weight to portray fit characters in films such as Moneyball (2011) and Zero Dark Thirty (2012), and had given up ambitions to play the lead role in action films after humbling auditions for Star Trek and Avatar (both 2009). Casting director Sarah Finn suggested Pratt to Gunn, who dismissed the idea despite struggling to cast that role. Despite this, Finn arranged for a meeting between the two, at which point Gunn was immediately convinced that Pratt was perfect for the role. Pratt also won over Feige, despite having gained weight again for Delivery Man (2013). Prior to filming, Pratt underwent a strict diet and training regimen to lose in six months. Pratt signed a multi-film contract with Marvel, and was granted a temporary leave from his work on Parks and Recreation to accommodate his participation in the film. Wyatt Oleff portrays a young Quill. Zoe Saldaña as Gamora:An orphan from an alien world who seeks redemption for her past crimes. She was trained by Thanos to be his personal assassin. Saldaña said that she became Gamora through make-up rather than computer-generated imagery (CGI) or performance capture. On taking the role, Saldaña said, "I was just excited to be asked to join by James Gunn and to also play someone green. I've been blue before [in Avatar]". Saldaña described Gamora as "... a warrior, she's an assassin and she's very lethal, but what saves her is the same thing that can doom her. She has a sense of righteousness. She's a very righteous individual". Dave Bautista as Drax the Destroyer:A warrior who seeks to avenge his family's death at the hands of Ronan. On relating to the character, Bautista said, "I can just relate to Drax so much it's not even funny. Just the simple things that we have in common. Simple things like the tattoos, the tragedy—because, you know, I had a bit of tragedy in my life, as well. So it's really easy for me to pull from that". Bautista also said that there was "a lot of comic relief to Drax", but the character was not aware of it. Bautista stated that he did not do much preparation for the role, because "Luckily, for me, I'm a lifelong athlete and I adapted real quick". Bautista's makeup took approximately four hours to apply, though it could be removed in just 90 minutes. Drax has various scarring patterns on his body, which replace the simple tattoos from the comics, each having a specific story. Additionally, his skin tone was changed from the bright green in the comics to a muddier gray, to avoid visual similarities to the Hulk. Vin Diesel as Groot:A tree-like humanoid, who is the accomplice of Rocket. Diesel stated that he provided the voice and motion capture for Groot, after originally being in talks to star in a new Phase Three Marvel film. Diesel also provided Groot's voice for several foreign-language releases of the film. Krystian Godlewski portrayed the character on set, though his acting was not used in the final character CGI. On the character, which Gunn based on his dog, Gunn said, "All the Guardians start out the movie as bastards—except Groot. He's an innocent. He's a hundred percent deadly and a hundred percent sweet. He's caught up in Rocket's life, really". Gunn added that the design and movement of Groot took "the better part of a year" to create. Gunn added, "The ways in which Vin Diesel says, 'I am Groot,' I am astounded. All of the 'I am Groots' that were earlier voices didn't sound very good at all ... Vin came in and in one day, laid down all these 'I am Groot' tracks, and he's a perfectionist. He made me explain to him with ever 'I am Groot,' exactly what he was saying ... It was amazing when we first put that voice in there how much the character changed and how much he influenced the character". Regarding the limited words used by Groot, Diesel said in many ways this was, "... the most challenging thing to ask an actor to do". Diesel found an emotional note in his performance, invoking the death of his friend and Fast & Furious co-star Paul Walker, saying, "This was in December , and the first time I came back to dealing with human beings after dealing with death, so playing a character who celebrates life in the way Groot does was very nice". Groot's form and size-changing abilities are seen, with Gunn stating that he has the ability to grow in the film.
