Avengers: Infinity War – Complete Cast and Character Guide

Avengers: Infinity War is one of the most ambitious movies ever made, with a cast of characters bigger than just about any cinematic event. In terms of the sheer number of stars gathered from all corners of Hollywood to appear in one picture, the only comparison is the epic 1963 comedy, It’s a Mad, Mad, Mad, Mad World. Practically every main character (and many supporting figures) from every corner of the MCU have assembled to take on Thanos and his Black Order in the ultimate battle over the fate of the universe… Well, until 2019’s Avengers 4, that is.

As the culmination of ten years and eighteen films from Marvel Studios, Infinity War is an important moment in blockbuster cinema, the and its significance cannot be understated. Even with Avengers 4 on the horizon, Infinity War is a cultural event like few others.

Before the release of the biggest motion picture event of the year, it’s time to take a look at the massive roster Marvel has assembled for the third Avengers film.

Note: this cast guide is spoiler-free, with any additional, non-announced appearances that may be in movie not discussed.

The Avengers

Robert Downey Jr as Iron Man – The first MCU hero, Downey made his debut in 2008’s Iron Man. Including his brief cameo appearance in The Incredible Hulk, Infinity War marks Downey’s ninth appearance as Tony Stark, the billionaire playboy philanthropist with a fancy suit of armor.

Chris Evans as Captain America – The erstwhile leader of The Avengers, Steve Rogers was last seen in Wakanda, an international fugitive due to his refusal to sign the Sokovia Accords, as seen in Captain America: Civil War. Chris Evans has said Avengers 3 and 4 will be his final appearances as the star-spangled hero, but has since backtracked on his comments.

Chris Hemsworth as Thor – After the destruction of his iconic weapon, Mjolnir, Thor recovered, proving he is not the God of Hammers, but the God of Thunder. The former prince of Asgard finally took his rightful place as king after Surtur instigated Ragnarok and destroyed his realm. Asgard is not a place, it’s a people.

Mark Ruffalo as Hulk – Although Edward Norton originated the character in the MCU, Mark Ruffalo took over for 2012’s The Avengers, and Hulk became a breakout star of the series. Unfortunately, it seems legal issues with Universal are currently preventing a new Hulk solo film from coming to fruition, but fans continue to hope.

Chadwick Boseman as Black Panther – Wakanda was first hinted at in an Iron Man 2 Easter Egg, but T’Challa himself didn’t make his big screen debut until 2016’s Captain America: Civil War. His 2018 solo film was worth the wait, and defied the odds to become the highest-grossing MCU film of all time domestically with an astonishing haul of $682 million and counting.

Benedict Cumberbatch as Doctor Strange – Stephen Strange was a gifted surgeon before a horrific car accident destroyed his hands and sent him on a journey to learn magic from The Ancient One. Now known as the Sorcerer Supreme, the good Doctor protects New York from mystical threats beyond the comprehension of the more literal-minded Avengers.

Tom Holland as Spider-Man – Back in 2008, few could have imagined that the friendly-neighborhood wall-crawler would swing his way into The Avengers, but it happened! Tom Holland made his MCU debut alongside Black Panther in Civil War before headlining his own film, Spider-Man: Homecoming, with Robert Downey Jr playing a supporting role.

Scarlett Johansson as Black Widow – Despite making her MCU debut all the way back in 2010’s Iron Man 2, and playing a prominent role in 2014’s Captain America: The Winter Soldier, Natasha Romanoff has yet to receive her own solo film. Scarlett Johansson is one of the most popular actors on the planet, and Black Widow has a mysterious and unexplained backstory, so what is Marvel waiting for?

Don Cheadle as War Machine – Terrence Howard did a fine job in the original Iron Man, but when he was recast for the sequel, most fans agreed that Don Cheadle was absolutely perfect in the role. While many enjoyed the star-spangled Iron Patriot armor from Iron Man 3, the character reverted to the metallic silver color scheme in Age of Ultron… and then broke his spine in Civil War. It happens.

Paul Bettany as Vision – Neither fully machine nor fully human, Vision was formed from a mix of vibranium flesh, Ultron’s genius, the other-worldly powers of the Mind Stone, and brought to life with a bolt of lightning summoned by the mighty Thor. Actor Paul Bettany surely had no idea he’d become an Avenger when he first signed on to do voice work for a minor role in Iron Man.

Elizabeth Olsen as Scarlet Witch – The product of Hydra’s experiments with the Mind Stone, Scarlet Witch and her brother, Quicksilver, were taken in by Ultron before seeing the error of their ways and aiding The Avengers during the battle of Sokovia. Civil War hints at romantic developments between Scarlet Witch and Vision, but it remains to be seen if the two will truly become a couple.

Anthony Mackie as Falcon – One of the breakout stars of the MCU’s Phase 2, Avengers fans were miffed when Falcon didn’t show up to kick butt alongside War Machine during the Battle of Sokovia in Age of Ultron. Still, he made up for it with his unexpected cameo in Ant-Man, in which he did battle with the diminutive hero.

Sebastian Stan as White Wolf – Formerly known as the Winter Soldier, Bucky Barnes was Steve Rogers’ childhood friend before he was captured by Hydra and brainwashed into being their assassin. In Civil War, his metallic arm was destroyed by a blast from Iron Man’s lasers, but the Wakandans have apparently built him a new one. Based on the post-credits scene of Black Panther, he now goes by White Wolf.

The Guardians of the Galaxy

Chris Pratt as Star-Lord – When the film was first announced, many feared that Guardians of the Galaxy would be Marvel Studios’ first box office bomb. They were wrong! The film was a massive success, and it turned Chris Pratt into an overnight A-List superstar. Star-Lord is a boy-ish hero with juvenile sensibilities but a good heart, and his special skills include crack marksmanship and an encyclopedic knowledge of 1980s pop culture.

Zoe Saldana as Gamora – In Avatar, Zoe Saldana was blue. In Guardians, she’s green. Gamora was Thanos’ favorite adopted child/spoil of war, but she turned against her evil father figure after years of enduring his cruelty and bloodlust. She’s working on rebuilding broken bridges between her and her sister, Nebula.

Dave Bautista as Drax – In the first Guardians of the Galaxy, Drax began his quest to avenge the deaths of his wife and child. After successfully aiding in the death of Ronan the Accuser, he directed his vengeance towards his true enemy, Thanos. Thanks to his charismatic performance, Dave Bautista went from a B-tier WWE fighter to one of the most in-demand beefcake actors in Hollywood.

Bradley Cooper as Rocket – Rocket Raccoon is a mysterious science experiment with a major chip on his shoulder. Over the course of the two Guardians of the Galaxy movies, he learns to love his adopted family and shipmates. Bradley Cooper, best known for leading roles in American Sniper and The Hangover, imbues the character with mischievous charm and punk-rock attitude, although credit must also go to on-set double Sean Gunn.

Pom Klementieff as Mantis – A recent addition to the team, Mantis debuted in Guardians of the Galaxy Vol 2 as the adopted daughter of Ego, Star-Lord’s biological father. These days, she rides with the Guardians. Pom Klementieff is somewhat unrecognizable with Mantis’s antennae and pitch-black eyes, but the lovely and talented actor can also be seen in movies like Ingrid Goes West and the ill-advised Oldboy remake, alongside Thanos himself, Josh Brolin.

Vin Diesel is Groot – After the release of Guardians of the Galaxy, Groot became something of a cultural phenomenon. His status was only exacerbated by the introduction of his offspring, Baby Groot, in Vol. 2. The character is voiced (in sixteen languages!) by Vin Diesel, whose Fast & Furious series is one of the biggest – and loudest – action sagas of all time.
