David Corenswet has begun intense physical preparation for his role in the upcoming sequel, Superman: Man of Tomorrow, as filming is set to start in April. The actor, known for his transformation into the Man of Steel, was recently spotted working out with his personal trainer, Paolo Mascitti, signaling that production momentum is building ahead of the movie’s release.
Early Signs of Superman: Man of Tomorrow Production Ramp-Up
Following confirmation by Nicholas Hoult, who portrays Lex Luthor, that filming would commence this spring, updates about the sequel have been scarce. However, recent images shared by Paolo Mascitti, Corenswet’s trainer during his DCU debut, reveal the actor undergoing a rigorous workout regimen. Fans have eagerly shared the photos, interpreting them as clear evidence that Corenswet is actively preparing to return as Superman. The commitment seen in these training sessions reflects the high expectations for the character’s role in the forthcoming film.
One fan on social media remarked,
“With David Corenswet back in Superman shape and filming this April, the hype for Man of Tomorrow is real. James Gunn says this isn’t just a sequel; it’s a deep dive into Clark and Lex’s dynamic. Seeing David get back to ‘fighting weight’ makes me think the action in this one is going to be on a whole different level,”
displaying anticipation for a more intense portrayal of the superhero. Others have praised Corenswet’s dedication:
This also means intense workouts, strict diets… all for the sake of delivering that perfect Superman performance. Respect!
and offered encouragement with messages like
“Rooting for you and your training, David Corenswet!”
David Corenswet’s Dedication to Becoming Superman
Corenswet’s transformation for the first Man of Steel involved significant physical demands, guided by Paolo Mascitti. To embody the iconic superhero, the actor adhered to a strict dietary plan, consuming around 6,000 calories daily to gain the mass needed to authentically fill out the Superman suit. This regimen increased his weight from approximately 200 pounds to 240 pounds.
The training included two-hour daily sessions centered on compound lifts and squats designed to build muscle and definition. Mascitti revealed that due to pandemic restrictions and other challenges,
“half of his training had to be done over FaceTime,”
highlighting the resilience and adaptability behind Corenswet’s preparation. The recent return to in-person workouts suggests a focused effort to replicate and perhaps expand upon that physical condition for the sequel.
Upcoming Filming and Release Timeline For Man of Tomorrow
While the exact date when Corenswet resumed training with Mascitti is not public, the proximity of the anticipated production start in April makes his return to the gym crucial. This disciplined preparation period follows a similar approach taken before the original Superman film’s production began five months earlier.
The sequel is scheduled for release on July 9, 2027, strategically positioned within the DCU film slate. It follows the 2026 premieres of Supergirl and Clayface, further expanding the interconnected storylines. Man of Tomorrow will hit theaters before Matt Reeves’ The Batman Part II, which is set for release on October 1, 2027, marking more than five years since the first Batman film was released.
Key Cast Members Returning for the Sequel
Alongside David Corenswet as Superman, the sequel will feature Nicholas Hoult reprising his role as Lex Luthor. Rachel Brosnahan is set to return as Lois Lane, while Frank Grillo will appear as Rick Flag Sr. This ensemble signals a continuation of the intricate character dynamics introduced previously and hints at a storyline deeply connected to the overarching DC Universe.
As production approaches, fans and critics alike remain cautiously optimistic about the project’s potential, especially given Corenswet’s dedication to embodying the Man of Steel once more. His intense preparation underscores the importance of authenticity and physical presence in bringing Superman back to life on the big screen.
