Joseph Quinn, known for his role as Johnny Storm in the Marvel Cinematic Universe’s recent phase launch with The Fantastic Four: First Steps, is now deeply involved in filming Avengers: Doomsday in England. As production continues, Quinn has expressed admiration for MCU veteran Robert Downey Jr., who returns in a villainous role as Doctor Doom, highlighting the leadership Downey Jr. brings to the ambitious project.
Avengers: Doomsday is currently underway despite delays, assembling a large and talented cast. The film offers the Fantastic Four the opportunity to collaborate closely with established MCU stars. Quinn has specifically praised Downey Jr. for his generosity and guidance on set, remarking on how the experienced actor contributes both humor and professionalism to the production environment.
Experienced MCU Stars Shape the Film’s Team Dynamics
While the cast of Avengers: Doomsday is extensive, Joseph Quinn shared that he has formed strong bonds with several co-stars during filming. Social media posts have revealed the cast spending time together off-set, attending meals and watching movies like Thunderbolts as a group. This camaraderie among the actors, including Quinn and veterans such as Chris Hemsworth and Vanessa Kirby, suggests a collaborative spirit that could enhance the movie’s chemistry onscreen.
Robert Downey Jr.’s presence as a leader is especially noteworthy given his long history with Marvel Studios. From his groundbreaking role as Tony Stark/Iron Man to multiple appearances across the MCU timeline, Downey Jr. brings unparalleled experience. His portrayal of Doctor Doom marks a new chapter as he takes on a villain for the first time in the franchise.

Expectations Surround Fantastic Four’s Role and Connection to Doctor Doom
The Fantastic Four are expected to play pivotal roles in Avengers: Doomsday, and their storyline is likely intertwined with Downey Jr.’s Doctor Doom. Since Doom traditionally opposes these heroes, fans are eager to see how their rivalry unfolds. Although it is unclear how many shared scenes have been filmed, Quinn’s observations of Downey Jr.’s leadership indicate a well-organized set geared toward bringing this dynamic to life.
Alongside Joseph Quinn as Johnny Storm, key cast members include Vanessa Kirby as Sue Storm, Ebon Moss-Bachrach portraying Ben Grimm (The Thing), and Chris Hemsworth reprising his role as Thor. Their involvement strengthens the narrative by blending new and familiar faces within the MCU’s expanding universe.
The Road Ahead for Robert Downey Jr. and the Marvel Cinematic Universe
Though Iron Man’s story concluded in Avengers: Endgame, Robert Downey Jr.’s return as Doctor Doom signals his continued importance in the franchise’s evolving plotlines. Marvel Studios president Kevin Feige has indicated that many iconic characters, including Iron Man, may be recast for future films such as Avengers: Secret Wars. For now, Downey Jr.’s role in Avengers: Doomsday offers audiences a chance to experience his talent anew while witnessing the veteran actor’s leadership influence the production.
Joseph Quinn’s positive remarks about Downey Jr. underscore the significance of experienced actors guiding newer talent during major film projects. As Avengers: Doomsday progresses toward release, this blend of veteran mentorship and fresh energy could deliver another blockbuster event for Marvel fans worldwide.
