‘Ironheart’ stars react to sweet live TV surprise from fellow Marvel star Robert Downey Jr.

Robert Downey Jr. has welcomed fellow Marvel stars Dominique Thorne and Anthony Ramos into the permanent MCU family with an iron-clad embrace.

The longtime Iron Man and Avengers franchise actor — who will return to the MCU as Doctor Doom in the upcoming Avengers: Doomsday — surprised the Ironheart TV series actors with a sweet message of support during a live interview on Tuesday on Good Morning America.

“Do you mind if we interrupt the interview for just a moment, because I think we have a very special message. I think you’re going to recognize who this is,” Robin Roberts said, before the show cut to a clip as Thorne and Ramos watched.

“Ms. Thorne, I couldn’t be happier than to be seeing you bring Riri Williams to life,” Downey Jr. said in the pre-recorded message, before turning his focus to Ramos’ upcoming role as the mysterious Hood in the Black Panther offshoot. “But, the Hood has me nervous. Is the hood green? Please tell me Mr. Ramos is not replacing me as Dr. Doom via Parker Robbins. Is there something they’re not telling me?”

The Oscar winner finished the video by making a heart with his fingers, telling the pair, “Long story short, Iron Man loves Ironheart.”

Back in the GMA studio, Thorne flashed the same symbol with her hands as she said, “Ironheart loves Iron Man too.”

She added that Downey Jr. “has been so supportive” throughout the making of the Ryan Coogler-produced Ironheart series, which follows her as Williams, Black Panther: Wakanda Forever‘s visionary inventor, who returns to Chicago to attend MIT — where she crosses paths with “The Hood” and ultimately constructs an iron suit to establish herself as the titular hero.

“It’s really been amazing because I come from a family that loves the MCU. My baby brother was born just a few months before Iron Man came out, it’s been a family affair ever since then,” Thorne continued. “We have pictures of my baby brother being Iron Man and me being Iron Girl for Halloween, like, this goes so deep. So, shortly after we finished filming in Chicago is when I got the first phone call from [Downey Jr.]. He’s been so sweet, through and through. So, the support, it means so much. It really does.”

Earlier this week, Entertainment Weekly debuted a first-look image of RuPaul’s Drag Race icon Shea Couleé in her MCU debut as Slug, a mysterious character she says might harbor a secret identity.

“From my understanding, this version of Slug they’re presenting is someone who’s being referred to as a code name. I don’t want to give too much of their backstory away. They need an alternative code name to go by because there could or could not be some people looking for them,” Shea teases in an interview, while confirming that the character’s history as a drag queen will be seen in flashbacks throughout the new show.
