After years of hiding away, Samuel L. Jackson returns as Nick Fury (Samuel L. Jackson) in Marvel's upcoming six-part event series Secret Invasion. It's time for him to wage war against a new villainous faction of Skrulls led by Kingsley Ben-Adir's Gravik.

With Skrulls spreading across the MCU, this spy thriller is one you won't want to miss. Check out the trailer below for an exciting first look at this thrilling new series!

Nick Fury (Samuel L. Jackson)

Marvel's Secret Invasion's latest trailer gives us a rare look at its main character Nick Fury (Samuel L. Jackson). After being absent since Spider-Man: Far From Home, Nick is back to fight Skrulls in "one last fight" in this thrilling new clip.

In this official trailer for the series, we see Fury meeting Maria Hill (Cobie Smulders), who was first introduced in Captain Marvel, and Talos (Ben Mendelsohn). Together they discover that a group of shape-shifting Skrulls are taking over Earth - and Fury and his allies must race to stop them from taking control of our home planet.

Though this looks like a lighter spy thriller, viewers should be wary of any potential impact on the Marvel Cinematic Universe (MCU). The series will likely wrap up several threads from other characters within the MCU that have yet to be resolved, including Cobie Smulders' Maria Hill and Martin Freeman's Everett Ross.

However, we hope this upcoming series will show more of Fury's vulnerable side rather than his overly assertive persona seen in previous Marvel Cinematic Universe films. Jackson has said that playing Fury appealed to him because he can be both sides at once; we can expect that to be evident here too.

In addition to Jackson, the cast includes Maria Hill (Cobie Smulders), Talos (Ben Mendelsohn) and Don Cheadle's James Rhodes, known as War Machine. There are also new characters like Emilia Clarke's G'iah and Kingsley Ben-Adir's Gravik. The series is set to premiere on June 21 - check it out below!

Maria Hill (Cobie Smulders)

Cobie Smulders will return to the Marvel Cinematic Universe as Maria Hill in Secret Invasion. This Disney+ crossover comic event reunites her with Samuel L. Jackson's Nick Fury as they battle a faction of shape-shifting Skrulls that have been infiltrating Earth for years. New stars joining the series include Olivia Colman from The Crown, Kingsley Ben-Adir from Peaky Blinders and Emilia Clarke from Game of Thrones.

Maria Hill has featured in multiple MCU films, always remaining focused and direct despite working alongside an eclectic group of superheroes. In Joss Whedon's first Avengers film, Hill played an integral role.

She made a brief cameo appearance in Age of Ultron, when her character seemed more serious and focused than usual. She quickly directed the rest of the Avengers as they battled Ultron, and when she finally saw him, her physicality changed into warrior mode.

Maria doesn't appear in the main part of Avengers: Infinity War, but she does make a brief appearance during the post-credits scene when she and Nick Fury notice something strange while driving through New York City. This serves as evidence that Maria always looks out for her teammates and takes action when needed.

Although her screen time in the trailer is limited, Smulders' lighthearted take on her blink-and-you-miss-it appearance suggests she could be an important player in Secret Invasion. We can only hope she plays a larger role than what we've seen her play so far in other MCU films! If you want more of her, be sure to check out her appearance in Spider-Man: Far From Home.

Talos (Ben Mendelsohn)

Captain Marvel brought us one of Marvel Comics' beloved Skrulls - Talos - as played by Ben Mendelsohn.

In the movie, Talos was introduced to the Marvel Cinematic Universe in an unexpectedly humorous manner. He wasn't a shapeshifting Skrull, but he managed to impersonate Nick Fury without using any of his powers - an ingenious prank which certainly raised some eyebrows among fans.

Skrulls had been displaceed by the Kree war and were seeking a new home on Earth while posing as humans. In 2008, Secret Invasion comic event revealed that many of Earth's most influential individuals were actually secret Skrulls.

These evil skrulls have been stealing and reprogramming Earth's computers for years, and now it's up to the Avengers to stop them before they turn our planet into their playground. The Secret Invasion trailer provides a glimpse into this future, suggesting that even with all their might the Avengers may need to put forth effort in order to fight these shapeshifting aliens.

Another of Talos' Skrull colleagues in the film is Norex, a loyal second-in-command who helps his fellow Skrulls capture Starforce member Vers while disguising himself as S.H.I.E.L.D director Keller to avoid suspicion.

According to the official trailer, this tactic works but only for so long before someone notices that these clones aren't actually human. This leads to an intensification of Skrull's plans to invade Earth; Talos must help the team figure out how they can prevent them from taking over all of our planet.

War Machine (Don Cheadle)

Don Cheadle is back as James "Rhodey" Rhodes, better known as War Machine in Marvel's latest live-action series Secret Invasion. The longtime MCU veteran first played the character in Iron Man 2 alongside Terrence Howard and has since featured in Avengers: Endgame, Captain America: Civil War and more.

Cheadle hasn't been seen in the Marvel Universe since last year's Avengers: Endgame, but he may make an unexpected return in Disney+'s new live-action series Secret Invasion. According to @MarvelFlix on Twitter, Cheadle will play a key role alongside Samuel L. Jackson as Nick Fury, Cobie Smulders as Maria Hill and Ben Mendelsohn as Talos as they join forces against shapeshifting Skrulls.

Though it remains uncertain whether Marvel's upcoming series will see Nick Fury at odds with his former Avenging partner Tony Stark, we can expect it to be an incredibly dangerous time for Earth. As Skrulls invade our planet, Stark's weapons - which were featured in the Secret Invasion trailer - could potentially fall into the wrong hands.

That will likely put a great deal of strain on his character, who has never before been involved in such an intense conflict. So it is likely that he'll take the initiative and enlist all his Avengers teammates to join him in battle against Skrulls.

As you can imagine, it will be a momentous occasion when all those heroes come together again. That, and the fact that Nick Fury hasn't had to contend with Skrulls in some time, will make it all the more thrilling for MCU fans.

Veranke (Emilia Clarke)

Game of Thrones and Solo actress Emilia Clarke has been cast to star in the upcoming Disney+ series Secret Invasion. While it remains uncertain which character she will portray, some have speculated that she could portray Skrull queen Veranke.

Marvel Comics' Veranke was the ruler of the Skrulls. She was a religious fanatic who feared an ancient prophecy that foretold of their homeworld's destruction, Tarnax IV. When she attempted to alert her emperor of this, he sent her away to prison world Tarnax IV. Years later, Galactus destroyed Tarnax IV leaving Veranke free but soon returning her beliefs back to her original beliefs.

The Skrulls are a group of shapeshifting aliens who can take any form as long as it falls within their physical limits. Additionally, they use this power to mimic the abilities of heroes they impersonate.

They have also developed their science to duplicate any Skrull's powers, even those with superhuman senses or psychic abilities. The Skrulls plan to invade earth, creating fear in humanity and creating an atmosphere of mistrust among heroes.

Thankfully, the heroes managed to repel her invasion; however, her psychological warfare proved too powerful for them to ignore. She even brainwashed Tony Stark into believing he was the real Iron Man!

Norman Osborn ultimately kills Veranke during a battle, leading to massive upheaval within the Marvel Universe. It was later revealed that these heroes had been brainwashed into believing they were true superheroes and must band together in order to fight back against their new foes.
