Marvel's Ironheart release date, cast, plot and latest news

Once an ordinary crook, he gains powerful magical abilities and adopts The Hood as a pseudonym, before approaching Riri about an alliance that could give her all the money and resources she needs to thrive.

But to what extent will she compromise her morals by joining forces with such a dangerous and unpredictable figure? We'll find out when Ironheart premieres next month – with a triple-bill launch, no less!

Black Panther filmmaker Ryan Coogler is attached to the project as an executive producer, and it's little surprise that his name is prominently displayed in the Ironheart trailer, following the runaway success of Sinners.

If you're suitably intrigued, read on for everything you need to know about Marvel's Ironheart – including the confirmed premiere date on Disney Plus.

Marvel's Ironheart release date

Marvel's Ironheart will premiere on Disney Plus UK on Wednesday 25th June 2025, with the streamer recently confirming that the first three episodes will drop at once.

As has been the case with previous originals, the show will be releasing simultaneously around the world, meaning that new episodes appear on Tuesday nights in the US and Wednesday mornings (8am) in the UK (due to the time difference).

Ironheart has suffered considerable delays: originally eyed to release in late 2023, it underwent two months of reshoots last year and was affected by a broader Marvel rethink in which the studio sought to streamline its overwhelming output.

"Frankly, in all honesty, there was a mandate to kind of create as much as we could for Disney Plus as quickly as we could," said Marvel's head of streaming Brad Winderbaum (via Agents of Fandom).

"And then, there was a shift, and all of a sudden, we have to start spreading our release dates out. So, that really accounts for a lot of the delays."

At least there's not much longer to go now!

Marvel's Ironheart cast

Dominique Thorne stars in Marvel's Ironheart on Disney Plus, reprising her Black Panther: Wakanda Forever role of Riri Williams – a science genius who creates her own version of the iconic Iron Man suit.

Joining the acclaimed actor for this entry is In The Heights and Twisters star Anthony Ramos, who will play a magically empowered crime poss nicknamed The Hood (also known by his civilian name Parker Robbins).

Other big name additions to the Marvel Cinematic Universe for this miniseries include one-time Han Solo actor Alden Ehrenreich and Borat star Sacha Baron Cohen, although little is known about their roles at the time of writing.

Notably, Ehrenreich told Digital Spy in 2018 that he would only consider joining the MCU if the creatives were "really in love" with their project, as opposed to it being a "money thing" – so it's quite possible he was wowed by showrunner Chinaka Hodge.

Currently, there's little in the way of returning actors, with the only confirmed exception being Community star Jim Rash, who will return as the Dean of Massachusetts Institute of Technology (MIT) – first introduced in Captain America: Civil War.

Rash is one of several former Community cast members to land cameo roles in the MCU, thanks to their connection with directing duo Anthony and Joe Russo, whose career began on the sitcom before landing the Captain America and Avengers films.

The following cast members have been confirmed for Ironheart:

• Dominique Thorne as Riri Williams / Ironheart
• Anthony Ramos as Parker Robbins / The Hood
• Lyric Ross as Natalie
• Alden Ehrenreich as Joe McGillicuddy
• Manny Montana as Cousin John
• Matthew Elam as Xavier Washington
• Anji White as Ronnie Williams
• Shea Couleé as Slug
• Zoe Terakes as TBC
• Regan Aliyah as TBC
• Harper Anthony as TBC
• Shakira Barrera as TBC
• Rashida 'Sheedz' Olayiwola as TBC
• Sonia Denis as TBC
• Paul Calderón as TBC
• Cree Summer as TBC
• Sacha Baron Cohen as TBC
• Jim Rash as the Dean of Massachusetts Institute of Technology (MIT)

What is Marvel's Ironheart about?

The official synopsis for Marvel's Ironheart reveals that it pits "technology against magic when Riri Williams — a young, genius inventor determined to make her mark on the world — returns to her hometown of Chicago".

It continues: "Her unique take on building iron suits is brilliant, but in pursuit of her ambitions, she finds herself wrapped up with the mysterious yet charming Parker Robbins aka The Hood."

The six-part series is based after the events of 2022 blockbuster Black Panther: Wakanda Forever, which saw Riri intercepted by agents of the titular African nation after she became a target for inventing a vibranium detector.

"What I can say is that it is definitely is offering folks a deeper dive into this character, that I gather might have maybe piqued some interest," said Thorne, in an interview with Deadline last year.

Who is Riri Williams?

Riri Williams is a relatively new creation, having made her formal comic book debut in 2016's Invincible Iron Man #9.

Nevertheless, the character has become a major player in the short time since, getting involved in the major crossover event Secret Empire and joining the young adult superhero team The Champions, as well as leading her own solo title.

When she was first introduced, Riri was only 15 years old but had already established herself as an accomplished scientist with a full scholarship from the Massachusetts Institute of Technology.

Her advanced intelligence leads her to design and build her own suit of armour similar to that which is worn by Tony Stark – and it isn't long before she gets the billionaire's attention.

He ultimately gives Riri his blessing to keep using the suit, making her as a major new ally; of course, this part of her origin was tweaked for the MCU, following Stark's sacrifice at the end of 2019's Avengers: Endgame.
